Polytrol 1L with 250ml Spray Can
  • Restores the colour and appearance of dull and faded surfaces caused by exposure to sunlight, rain and pollution
  • Deep penetrating oil that restores the original look and

    finish to gelcoat, plastic, metal and other surfaces

  • Protects against corrosion and blemishes
  • On bare metals Polytrol restores the shine and protects against corrosion
  • Now available in a handy 250ml spray can

Polytrol is a deep penetrating oil which restores the original colour and appearance of dull or tarnished plastics, gelcoats, metals, and other surfaces.

It penetrates the surface, re-wetting the pigments to restore their lustre and colour which has been lost through exposure to sunlight, rain, and pollution and it also gives corrosion protection.  When used on tarnished metals, it brings back the shine and gives long-term protection against corrosion.

Simple to apply using a cloth or soft brush, it’s ready to wipe off in just 10 minutes! It can be used on both horizontal and vertical surfaces and can even be used on fibreglass (GRP). Polytrol dries to a tough and long-lasting flexible finish which does not leave a film – so it won’t peel or flake.

Polytrol is now available in a handy 250ml spray can, great for quick application and difficult to reach areas. Please see the directions for use to find out how to apply it.

Ideal Uses for Polytrol Colour Restorer

  • Brightening faded car bumpers
  • Reviving the gelcoat on your boat
  • Restoring the shine to metal fixtures
  • Rejuvenating flat or chalky paint dulled by weathering
  • Brightening the surface of tiles in stone, terracotta, marble, slate, etc.
  • Reviving the colour of faded garage doors


DO NOT use Polytrol on white surfaces, it will not work as Polytrol is designed to restore pigments.

Always read the Polytrol Product Information before using and follow the instructions carefully.

Surface Preparation

All surfaces must be clean, dry and free of dirt, grease, grime and mildew. All waxes, polishes, silicone etc. should be completely and thoroughly removed. Treat any mildew with a 50:50 bleach and water solution. Scrub the solution on to the surface and allow it to stand for 10-15 minutes then rinse thoroughly.

Using Polytrol on plastic, gelcoat, tiles, painted surfaces etc.

Clean the surface with warm soapy water or Net-Trol, rinse thoroughly and allow it to dry for a minimum of 24 hours depending on the surface.

Using Polytrol on stone, brick, etc.

Clean the surface with Net-Trol, rinse thoroughly and allow it to dry for a minimum of 24 hours depending on the surface.

Using Polytrol on metal

Clean the surface with warm soapy water and rinse thoroughly or use an appropriate solvent (follow manufacturer’s instructions). Leave the surface to dry for a minimum of 24 hours.

Application of Polytrol Colour Restorer

General directions

Always work in areas that can be completed 10-20 minutes to ensure an even appearance. If the surface absorbs the Polytrol unevenly (i.e. some matt and some shiny patches) move any surplus oil from shiny areas to matt areas. Wipe off any excess Polytrol with a lint-free cloth before it becomes tacky. For a shinier finish, buff the surface with a lint-free polishing cloth.

When using the Polytrol 250ml spray can, simply spray on liberally, wipe off any excess and leave to dry.

Applying Polytrol to plastic, gelcoat, tiles, painted surfaces etc.

Apply Polytrol liberally and evenly with a brush or cloth. Allow it to work for 10-20 minutes. Wipe off any excess with a clean lint-free cloth. Leave it to dry.

Applying Polytrol to stone, brick, etc.

Apply Polytrol liberally and evenly with a brush or cloth and leave it to work for 10-20 minutes. Brush out or wipe off any excess Polytrol with a clean lint-free cloth. Leave it to dry.

Applying Polytrol to metal

Apply Polytrol using a fine wire wool (000 grade) soaked in Polytrol and allow it to work for 10-20 minutes. Wipe off any excess Polytrol with a clean lint-free cloth. Leave to dry.

Note: Polytrol is not a surface coating. Its place is in the surface, not on top.


Maintenance is due when a Polytrol treated surfaces shows signs of fading. Prepare and re-treat surfaces as directed above.

Clean Up

Clean any tools used with white spirit. Polytrol is non-flammable, however any rags, steel wool etc. soaked in Polytrol may spontaneously catch fire if improperly discarded. Rags, steel wool etc must be saturated with water after use or placed in a sealed, water-filled metal container, before disposing of them with household waste. Rags may be laid flat and air-dried before discarding.

Things to Remember

  • Cover and protect everything you do not wish to treat.
  • Apply between +5°C and +35°C.
  • Do not apply in direct sunlight or on to hot surfaces.
  • Do not allow excess Polytrol to dry and create a film on the surface (always remove excess product).
  • Do not use Polytrol on white surfaces.

    I am absolutely amazed at this product. I thought I would need a new composite door at a cost of £1,500++ as it was so faded and scratched. I bought this Owatrol colour restorer after seeing it on YouTube.
    Applied it with a cloth after thoroughly rubbing it down with a washing up scourer. Took about 20 minutes to apply. My door looks as good as new. Fantastic product.

    Brilliant stuff! Didn’t quite believe all the amazing reviews but did a fantastic job bringing our 17 year old badly faded wood effect GRP garage door back to life! Only used about half a 500ml tin, just washed the door, let dry and then wiped it in with a cloth. That was it and wow, what a difference in the before and after pictures!

    I purchased this product about 3 months ago and tried it out during the lockdown period. I applied it to the grey upvc surrounds to my windows, which are 4 years old and have suffered quite badly from the intense sunlight and heat that I get on both my balcony in the morning and in my backyard in the afternoon. I found that the product was about 90% successful in restoring the colour – perhaps the surrounds were a little too in far gone in patches to be any better. The material itself was easy enough to apply and the finish is really good and lasting. So I would recommend it notwithstanding the caveat above.

    Purchased a Litre tin some 2 years ago , I have a plastic wood grained garage door , couldn’t find anything that after application that lasted long, I live in a coastal area and the salt air is so damaging, I spotted this product and duly ordered , it takes me about 25 minutes to apply to my door , the results are transforming although I have to apply further coats probably about 3 to 4 times a year due to the severe weather conditions , I redid it again today with my last drop of the product and have just reordered another litre, there are 9 other garages in our block, they use just a car product for bumpers and they fade within 4 weeks of a refurb, highly delighted with your product ,many thanks .

    I was about to fork out £360 on having a badly faded garage door uPVC spray painted and then stumbled across Owatrol Polytrol. Despite the positive reviews, I still had my doubts, but at one tenth the price of a respray decided to shell out for a litre of the stuff in a “What-the-hell-let’s-give-it-a-go” moment. Well, even the positive reviews don’t do Polytrol justice. It’s ridiculously easy to apply, easy to clean up after and has left my garage door (and the door seals, which I also treated) looking as good as (if not better than) new. An outstanding product. I’d have no hesitation in using it again and have absolutely no hesitation in recommending it.

    Received my Polytrol on time.My black composite front door was extremely bleached as is situated south facing and in full sun. Had differing opinions about repainting but decided on trying Polytrol. Followed instructions and only took 20 minutes as easy to apply. I am delighted with the result as the door looks brand new and all blemishes and faded areas were easily covered and only used quarter of my half litre tin. Would certainly recommend. One of the best products on the market.

    Polytrol, is an absolutely fantastic product. My garage door was getting quite faded so I purchased a tub 1ltr (way too much for one garage door). It was so easy to use, just apply with a cloth (just like cleaning the door with a damp cloth). It was so easy that I didn’t have a lot of confidence that it would work, but after drying, it looked absolutely great. I have just, two years later, redone the garage door and again had a fantastic result. I can’t praise it enough (I am so used to products not living up to expectations and this was a very pleasant exception).

    My green fibreglass observatory was looking very faded and dull after four years of exposure to the elements. The manufacturers recommended Polytrol to restore it to its former glory, so I ordered a one-litre can. I treated the whole structure with just half the can and have to say I am delighted with the results. It now looks like new again, with no trace of tarnishing and the colour has been restored to a deep lustre. 👍🏻

    Bought this to revive the bumpers on my vw transporter, I have used lots of products that say they bring them back as new but none of them lasted for more than a month !
    I was so impressed with the results I used it on a composite door in my street and the owner
    was so happy they wanted to pay me ! what a bonus that payment paid for the 1ltr tin that I had bought, And I still have 3/4 of the product , will be on the lookout for more front doors and who knows it might be a nice little earner.

    Fantastic product I only bought the sample pot as I was a bit skeptical as to whether it would work. We have had a Keter garden storage box for 3 years which the lid has faded due to the sunlight the problem was that we bought a new one to go next to our original one and as I have a bit of ocd the fact that the lids were different colours I wanted to replace the older one so they would match but my husband wasn’t willing to spend another £110.00 for no reason so I googled plastic colour restorer and found your product and now I have two matching boxes for just £5.00. I will definitely recommend to all our family and friends who are in need of restoring rather than buying new items.

    I ordered a sample pot and DHL delivered it elsewhere – but Owatrol were quick to replace, thank you.

    I’ve used it today and my grey composite front door is as good as new and I’ve hardly used any from the pot. Easy to apply – I used a lint cloth and just wiped it on the clean door. Waited 20 minutes and buffed off. Easy and effective. Looks like a new front door.

    My uPVC front door had faded badly and being a mahogany finish it looked terrible. I bought this thinking it certainly couldn’t look any worse. Applied it with a soft clean cloth and it dried brilliantly. Looks like new again. So good that I’m going to have to change the letterbox now!

    The Polytrol was originally for reviving composite doors which did a great job. That was such a success I decided to have a go at these old tired green garden chairs. You can see the result.

    They were washed down with soap and water, then left to dry. The polytrol was then sprayed on and spread around with cloth.
    I am still amazed every time I look at them and have recommended the product to many friends.

    I was very sceptical about all the positive reviews of Polytrol when I found the product on the internet. I was contemplating having to replace my composite rosewood effect front door because it looked so chalky and faded. I had tried all sorts of products to try to restore the original finish but none worked. As a final try, I decided to buy some Polytrol.

    The product is easy to apply by brush but don’t let it dry for too long before wiping the surplus off with a lint-free cloth. I must say that the positive reviews were justified and my door looks almost like new and I’ve got plenty of Polytrol left for when it needs re-coating.

    Recently noticed that my Brown Composite Front door was becoming very “Faded” in the recent sun. Asked the original supplier for any tips to restore the colour and got no help at all.

    Having trawled the net I found Owatrol / Polytrol and gave it a try! Almost like magic the colour was restored in no time at all so I can highly praise your product for a quality result with minimal effort and no “Glitches”.

    Many thanks.

    Our mahogany composite front door(south facing) was ten years old and just out of warranty….although I don’t think the company would have replaced it….and was quite badly faded. However, the door company recommended Polytrol and like other reviewers I wasn’t willing to pay almost £2000 for a replacement !!!!
    Followed the instructions and it worked. The neighbours thought we had a new door.
    Most impressed and hope it will last as the sun can be pretty strong ….. am I able to redo at a later stage if it starts fading again ??
    Thanks for saving me a lot of money !!!

      You can re-apply Polytrol if the surface stars to fade again. Simply clean the area, wait for it to dry and then re-apply the Polytrol in the same way you did before.

    Absolutely outstanding product. I have a 22 year old Ifor Williams horsebox trailer and have been looking for months for a product that would cover / Treat or restore the faded painted side panels. Some of these panels had transfers applied by previous owners. These I had removed which left a darker silhouette on the panels where they had faded around them, which further made the trailer look shabby.
    I bought a sample pot of Owatrol colour restorer to try following reading reviews and watching the product video showing its use, hopefull but still not fully convinced it would work. The results on a test patch were awesome the rich red colour was remarkably restored in minutes. I tried it then on the aluminium roof panels , fantastic , shiny like new. I then cleaned the mould of the grey fibreglass front roof panel and was amazed with the same brilliant result of a rich colour returned almost as new. I promptly purchased a Litre of the stuff and set to work on the whole trailer . I and my family are absolutely amazed by the transformation, I am seldom lost for words, but the ease of use, simply brush applied to a clean and dry surface, then wiped over with a cloth to smooth out an even coating, then left to dry , the results have astounded me.
    I took before and after photos which I will gladly forward as proof.
    Recommend it to anyone . Worth every penny . Does exactly what it says on the tin!!!.

    I had a very faded 10 year + composite front door and was about to buy another door for which I was quoted over £1000. I searched the Internet for any product that would enable me to paint the door over temporarily to make it look a little better for a while and came across Owatrol Polytrol.
    I was very sceptical of all of the reviews as I did not think that there was any product that would do the job and could be as good as the reviews stated. How wrong I was. I purchased a 1/2 litre tin of Polytrol thinking that it was worth a try (anything was better if it worked rather than spending over £1000). I washed the door down as per the instructions, let it dry overnight and painted on the Polytrol wiping off any excess as I went. The results were fantastic and all of my neighbours have asked where we bought our new door from. I would certainly recommend this product to anybody . Well done Owatrol. A fantastic product that does what it says on the tin.

    Absolutely amazed at how this brought our door up.
    We have a red composite door, my hubby decided to clean it with kitchen cleaner with bleach in it. It took the shine off and the patches where he had scrubbed looked terrible.
    Took him just a few minutes to redeem himself by applying Polytrol. A little went a long way and still have plenty left should he decide to clean anything else with bleach !! The door looks better than new, so pleased I tried this before having to replace or repaint the whole door.
    This was quite a few weeks ago now and its been rained on and had the hot sun on it and still shining
    Thank You very much Polytrol.

    My composite door had faded quite badly due to being in full sun for the better part of the day. Had looked at getting it painted which came in at approx £250.00. After further googling i found Owatrol Polytrol. Was a bit dubious for a start how this could work, but after applying and waiting for it to dry was absolutely amazed at the result. The door now looks like it did when first installed. If you haven’t tried this you are definitely missing out on a superb product

      Thank you for your comment regarding your experience with Polytrol.

      We are sad to hear that you are experiencing fading after such a short period of time.
      We would suggest that when you re-apply that you leave it on the surface for a little while longer – the recommendation is to allow it to work for between 10 and 20 minutes.
      Perhaps leaving it on the surface for closer to 20 minutes will give you the desired finish that you are looking for.

      I hope this was helpful – please don’t hesitate to contact us should you require assistance.

      All the best,
      The Owatrol Team

    My front door had been badly faded by the sun and really didn’t think there was anything on the market that could bring it back to life. I read the reviews and was dubious it would work so bought the small 500ml tin and really didn’t need that much as it is a liquid and a small amount goes a long way. Once applied I can honestly say the door now looks like new. I can thoroughly recommend this product but do wish it could have been purchased locally rather than having to buy online and get delivered.

    Unbelievable….. I thought i would have to but a new front door, as my dark green upvc door had become milky and very unattractive. I gave it two coats of owatrol and people ha e been asking me if I’ve had a new door. With two coats I got a deep glass shine and the original colour back. I then couldn’t help myself and ended up doing the garage door to match as well. A truly brilliant product …. I never review anything, but am astounded at how good this is and how easy and clean it is to apply.

    I purchased polytrol to try and revive my black composite front door. The door was looking dull, had a lot of fine scratches and a couple of really prominent scratches.
    I have to say the results are astounding ! My door looks almost new again. All the fine scratches have disappeared and the two bad ones are considerably improved. The door looks glossy and deep black again.
    Plus I still have plenty of the polytrol left to use again.
    I would definitely recommend this product. I’m so pleased with the results.

    Bought some Polytrol to restore the faded plastics on my 2001 Boxster. Lift the bonnet and it now looks factory fresh, and that’s several weeks after applying it. Also used to great effect on faded bumpers and trim on another car, huge difference to the appearance. Miles better than any high street ‘back to black’ product!

    Amazing! Our west facing 5 year old mahogany coloured PVC front door had faded badly and was quickly bleaching. We consulted the manufacturers who offered no solutions apart from a £2,000 replacement.
    With little to lose we tried Polytrol and were delighted with the instant improvement.

    Absolute miracle worker ! I have a red composite front door, only a few years old that had very quickly become faded, and dry looking, I had tried polishing it, washing it etc but it still looked awful, I was at the point of buying a new front door, when I googled the problem and found polytrol, I thought for the price I would give it a go before spending a fortune on a new door.
    I am so pleased I did, the door looks like new, its colour is restored and it has a lovely shine, I bought the 500ml and have loads left, I have also used in on the faded black car bumper /trim and that has been totally rejuvenated as well.

    I recently used this product on my wood effect GRP garage door which is probably at least 15 years old. The door had gone dull & patchy. I have gone over it once & the result is excellent. There are still a few dull smears & although they hardly notice I will go over them again in case I wiped it off too soon. Generally the door looks new again & I hope it will last. I can highly recommend this product to others, I am unaware of any other treatment to recover a GRP door.

    Amazing product. I used it on my very badly faded upvc guttering and it restored most of the surface to virtually new. I also used it on the upvc sill to my front porch, the surface of which was badly and unevenly faded, in some places shiny and in other places matt and worn. I was going to try to cover this somehow with a upvc moulding but after using your product it now looks virtually new again and has saved me a job that I was not sure how to do. Glad I found your product.

    Always a bit skeptical about products with wild claims, I thought a sample pot isn’t too expensive for a try so why not. It was to be used on an old vintage Lambretta, which had clearly lived outside most of it’s 57 yrs, and as a result the original cellulose paintwork had became very sun bleached. I’m not sure exactly what happens, but it did restore the paintwork back to nigh on factory colour and after 10 minutes as claimed. I applied with a clean lint free cloth. After a day I applied a wax finish which took 3x longer than applying polytrol. I have only awarded it 4 stars simply because the long term durability in my instance, hasn’t been determined yet. But I will be using it on a regular basis.

    I saw this online. Despite being sceptical I decided to give it a go on my red composite front door which has had 10 years of south facing sun and extreme weather conditions. It was looking very lack lustre to say the least. I was excited but nervous to use it. No need!-an incredibly easy product to use with incredible instant results!!. White grainy streaks and dullness gone To be replaced by a rich shiny deep red colour. I’m so amazed I have to keep going out to look at it. So chuffed. Can you tell me polytrol team if I can apply this again to the same surface if it again fades in the future?

      Owatrol Team

      Hi Di,

      We’re so pleased that you’re happy with the results obtained by using Polytrol. You can indeed use Polytrol again if the door becomes faded again so long as there are still sufficient pigments in the substrate. Essentially Polytrol is restoring the pigments so if the surface is very badly damaged it may not be successful but usually it is. We would anticipate you having similar results if you used it again in a few years.

      Many thanks,

    I bought this to use on a faded dark red composite door. Washed the front door down with sugar soap and painted it on once the door was dry.

    Took about 15 mins effort and the difference is amazing after just one coat. So much easier than sanding door down and then repainting.

    I would upload the photos if I could.

    Polytrol is the elixir of life…for my mahogany upvc windows!
    We looked at replacing the windows as the sills had been bleached white by the sun.
    My wife then found this on the internet and because of the reviews we thought we would give it a try.
    Thank goodness we did…without exaggeration a miracle happened right in front of our eyes.
    Polytrol was extremely easy to apply with a sponge and it immediately returned our windows back to their original colour and lustre.

Initially I thought I’ve spent too much on this product but in fairness it is worth it. I applied it too my 16 year old discovery to give it a new lease of life and it’s done just that.. that was one application 4 weeks ago and the black plastic trim looks just out of a show room.. really pleased.

    I had a pretty tough job for this stuff – a weathered grey roof box that’s been stored outside for some time. It had become patchy and mottled on top and i thought I’d try and restore the original colour. I cleaned first using owatrol as suggested, then after it dried I used the Polytrol to polish. It made a big improvement but some the more serious patches remained so not perfect. This is a good product but probably better suited to more uniform wear and tear rather than patchy damage.

    The mahogany coloured upvc window sills, at the front of my bungalow, had become white due to facing the direct sun light day in day out. I thought that I would have to replace the units, they were so bad. I happened to see Owatrol advertised on line and after reading the numerous reviews, all of which were very complimentary, I thought it worth a try.
    Thank goodness I did. One application has restored the colour and surface like new! I’m so impressed that I’ve since given all the upvc fixtures a protective coat.

    The product, Owatrol Polytrol was recommended for restoring some colour to some red plastic bathroom ware, in particular a bathroom cabinet and brush holder. Because of their position in the bathroom they come under direct sunlight for almost half the day. While re-vamping the room it was decided to keep these rather than replace, but they had become faded over the years. Regrettably the product made little difference, fortunately I only purchased the 100ml tin, so there was little lose financially. I followed the instructions to the letter, even to the point of trying to build up layers over a few days.

      Hi Geoffrey,

      We are sorry that you have had a negative experience using Polytrol. If your substrate is particularly badly damaged and the piogmentation has faded to such a point that it is not recoverable then it is possible that Polytrol will not be able to recover it. We always recommend purchasing a sample to treat first which it seems that you have done, we are sorry that it hasn’t worked for you on this occasion.

    We purchased polytrol to see if it would bring the paint finish back to what it was originally on our 57ft narrowboat.
    After previously spending hours on end of waxing previously, the boat never looked really shiny and was always left a bit chalky no matter what wax we used.
    I googled to try and find an alternative and came across polytrol. I e mailed their technical support team to check itvwas suitable for stainless steel and received a quick response. On ordering polytrol, delivery was very quick.
    We waited for a dry day to get the job done..it was so easy to apply..no more hard rubbing and buffing we pre iously had with wax..and the boat looks amazing..I would definately recommend polytrol to other fellow boaters.

    I have been in the motor trade all my life, some 34 years and have never come across a product like it. Its fantastic. It is not a surface dressing or scillicone like most others. I applied this to grey plastic skirts and trims on a 14 year old motor home on which NOTHING else would work, as you apply it with a paintbrush, within a minute you can see the colour darken back to the original grey, now
    looks new.
    Then used it on badly faded dark brown plastic bumber and trim on a Volvo XC 70. So bad that my only other option was to paint them to match the body, hundreds of pounds. An hour with this and all the trims are looking fantastic. It has been on the car a fortnight, has been washed twice and still looks like its just been applied. In a nutshell, it works, buy it, you wont be disappointed.

    Used it on a South facing and fading red composite front door and side panel. I had a shinier than new finish in minutes with just a quick brushed flash coat. As the product dried I had to touch up a few areas where I hadn’t quite got enough on, but that was easy and didn’t cause any issues. The result was as other reviewers say, the door was as good as new. Unfortunately it now shows the letterplate and handle up so I’m going to have to polish them. As I was on a roll and with time to spare I tried some on some satin black plastic trim around my 308 spotlight. It had suffered from a scrape which I had T cut but this had left a light patch on the plastic. I applied a tiny amount on a soft cloth and a little rubbing in and the trim was as good as the other side. I cannot comment on how long the effects will last but it appears to be a sound surface.

    This stuff is amazing. I wasn’t convinced but thought it was worth a try before considering replacing the area we wanted to cover. We had second hand decking installed on our static caravan and the slats were all sun bleached and faded. The polytron was almost magic, I took photos of an area we had done compared to the original and it was incredible! The decking is back to the brown colour it was originally. A small price to pay for what would gave cost £2k to replace. It also appears to withstand our dogs’ claws running across the decking.

    I bought this hoping that it would restore the colour to some old, faded, brown double glazed windows. I will be honest and say I didn’t hold out much hope. Boy was I wrong!! I could not believe the difference this made. I applied it using small amounts on clean rags, it was very easy to apply and a little went a long way. The window frames look fantastic now, gone is the sickly, dull pale brown appearance which has now been replaced by a deep, virtually origanal, lustrous brown.
    I will applying this all the windows now, it even bought the black trimmings on the car back to life! In short, believe what it says on the website, this stuff works!!

    Used Polytrol to refurbish two very faded mahogany effect fibreglass garage doors. Very quick to apply and gave a result possibly better than new. It goes a long way – I bought one litre and still have most of it left. I tried it on weathered brown uPVC guttering and it was good on that too. An excellent product.

    I’ve attached photos showing the three roller shutter garage doors before treatment with Polytrol and one photo of the the doors restored to their original colour and condition after treatment. The doors are a powder coated aluminium roller shutters and were installed in 1991. They are south facing and had faded badly with WD40 staining around the locks. We are delighted with the success of the treatment. They are now as good as new.

    A one litre can treated these 3 doors and my neighbour’s two garage doors.
    It also restored his faded brown guttering back to new condition.

    What a magic product. We never imagined that it would be so successful at such reasonable cost.

I have looked at all types of product to bring back the colour and this is the first I have seen that doesn’t coat the surface like a polish or varnish, but enhances the colour pigment.
    I started with a small area and an open mind. I was so impressed I continued over the remainder of the two sides, which now perfectly match the original colour of the unfaded sides, good cover too only half of the litre tin used for one end and a side plus decking hand rails of a 40′ X 13′ caraven
    I even had other owners queing up to ask what the product was and where to buy it.
    I am truly and utterly amazed at the transformation.
    Over a month now since the treatment and still perfect.

    I used your product on my Metal Garage door which was badly stained, I had tried other products to remove the discolouration but without success. The Owatrol returned the Door to it’s original colour and lustre and has completely refurbished it.
    It is now like new!

    Thank you.

    I was a bit apprehensive about the Owatrol Polytrol. I completely washed down my GRP garage door on Saturday evening. The following evening I went out armed with the tin, a brush and a clean microfibre cloth and off I went. OMG the stuff is amazing the whole thing took me about half hour. I had to keep going out and checking the door to make sure that nothing had gone wrong. This morning I went out and the door looks absolutely fabulous – it looks as good as when it was first fitted.
    Thanks a lot for a wonderful product.

    Bought this to restore my grp garage door. The rosewood finish had faded through sunlight quite badly. Cleaned and with one coat applied it looks like a new door! So impressed, cant recommend highly enough. I have a picture of half coated door that shows the result. Can send if you like

    Thought I would give this a try as my fibreglass wood effect garage door was looking very faded and sad! What a difference, the door looks like new. I wish I had taken a before and after picture as the improvement is so great it looks like I have a brand new door and it was easy to apply. The only reason I have not given it 5 stars is that the cost of the product with postage is a bit expensive but I am a bit tight!

    Brown upvc door had faded due to sun damage but this product did an amazing job and the door looks like new. Saved hundreds of pounds by not purchasing a new door.
    An amazing product and very happy that i purchased a tin.

    Our red composite front door was looking very tired with white streaks in the grain pattern across the bottom panel and all the way up the centre of the door and around the glass panels. I tried numerous different cleaners and a car colour restorer all with no improvement. I found Owatrol Polytrol with an internet search for a solution and ordered some as a last resort and am really glad I did. After little more than half an hour, around 50ml of Polytrol and a little elbow grease our door was looking as good as new. What a relief!

    Looked this up on the Internet and I’m glad I did.
    Was going down the paint side of bringing my garage doors back to life.
    They were dull with the sun and look awful.
    My neighbour went down the paint option and looked the way forward.
    Once I found this online it was ordered and arrived in a day or so.
    It takes no time at all to apply and my doors look like new!
    Awesome bit of kit!
    Highly recommend!

    I had a rather weathered looking fibreglass garage door. It had faded and lost all of its shine. After a bit of googling I came across Polytrol, looked good, ordered the 0.5 ltr pot which was ample. Applied as per the instructions and was surprised by how well the colour has returned to the garage door.
    What was an added bonus is that it does not mentioned fibreglass on the tin but did a superb job.

    Highly recommended

    I despaired that after 5 years of having a composite front door fitted on a new porch the black finish had lost it’s sheen due to sun damage and turned to a faded matt colour. I asked my decorator for advice but he couldn’t offer any tried and tested solution. So I researched ways in which to restore it but nothing was coming up…. until I came across this site and the product Owatrol Polytrol. I had nothing to lose and finally tried it out and with amazing results!!! I used a cloth, rather than a brush, to apply the oily fluid. Rubbed it into the surface not just over it, and 24 hours later after drying out, the door looked like a new door – Hallelujah! So pleased with the result.

    Highly recommended!

    This is amazing. Our composite oak coloured front door gets all the weather and was faded and flaky. We didn’t know how to deal with it but after searching the Internet found Polytrol. It seemed a bit pricey but cheaper than a new door so decided to give it a go. So glad we did – the door looks great, especially with a new letterbox. It’s not perfect but more than acceptable. Inspired by this success the black, iron outside wall lamp was treated, then the bird feeding station, the cars black trim and the boot scraper. We found ourselves looking around for other things to restore and the best thing is that you only need one product for so many different surfaces.

    Outstanding product, although it remains to be seen as to how long it will last before re-treatment is needed.

    I have a GRP garage door that was looking a little tired after 12 years of use, with not a lot of care given, so I was browsing the net to see if there was anything that might improve it’s looks,and I came across Owatrol Polytrol. I am SO glad that I did. What a great product this is, and I have now got a great looking garage door that looks brand new , plus great looking wood effect doors and windows, as well as my guttering and facias etc. I would really recommend this stuff to anyone. As they say in other adverts, it does exactly what it says on the tin, and then some. Many thanks , I would have liked to have sent you photos, but I don’t see any facility here to do so, anyway, many thanks . Brian

    My brown GRP front door has been blasted by the sun for the last 11 years. It was fading and looking dreadful.
    I used Polytrol as per the directions and, literally, it looks like new. It was actually easier to apply than the instructions suggested.
    I have since applied it to all my brown plastic windows and it they too are looking like new.
    I am not sure how long the improvement will last but so far the results have been brilliant.

    I’d given up thinking that I could restore two fibre-glass wood effect garage doors, one of which was particularly faded, but thought that this product was worth a “last ditch” try. The result of the first coat was impressive, but after two coats on one and three on the other, they really are “as new”. Time will tell if they weather quickly, but I’m quite happy to give them a quick coat once a year if they look this good.

    I used this to bring a tired looking GRP garage door back to life. The result after one coat was very good. So much so my neighbour thought we actually had our door replaced with a new door. Just make sure you prepare the door well by using an All Purpose Cleaner first.

    We had a faded, wood effect, glass fibre garage door. It is one of a pair, but only one is subjected to strong sunlight. We were apprehensive about buying the Polytrol, especially since the delivery charge is relatively high, however, after using the product, the garage door is no longer faded and matches the other door, which was not subjected to direct strong sunlight. Surprised and pleased with the result. The Polytol was delivered the next day, after the online order, the tin was well wrapped in bubble-wrap inside a cardboard box.

    Just used on wood effect fibreglass garage door installed 21 years ago, that has had no more than occasional washing and had become very sunlight bleached and faded. After a good wash the day before it took 40 minutes to treat and polish; results are startling… almost as good as it looked when I first installed the door. A stunning product; now getting ready to use on my wood effect window frames!!

    My GRP garage doors had faded over the years and looked quite dismal but after a single coat of Owatrol Polytrol they look brilliant and the colour has been revived to a lovely rich colour. Wish I had found out about this product earlier. Highly recommended. Delivery very quick and updates by email.

    I’m a decorator, I was asked by a customer if there was something I could do to make her faded, wood effect plastic garage door look better, it was a pinky/ orange colour. I suggested trying this product. The end result was amazing it looks like new. Since then I have done two more garage doors for her neighbours and had other people ask.

    My rating may be somewhat unfair but does reflect the outcome. This was a last ditch attempt to rescue a patchy faded composite door I suspect our problem was made worse because of a lacquer finish that has deteriorated to varying degrees across the door. Although have tried to remove the lacquer it still leave a colour patchy outcome. Convinces me I need to look to a respray solution – worth a try though.

    Having searched for products to restore my wood effect GRP doors, it looked like the only way to do so might be applying a new gel coat which would have been a long complicated job requiring removal of the doors. I stumbled on this product after almost giving up hope of finding anything suitable and I have to admit I was sceptical about the results other reviews claimed. However I thought that lacking any other ideas it was worth a try and I can fully endorse all the other reviews – the results are amazing considering there were previously large dull, almost white patches over the doors. After a single, effortless application the colour is restored and the doors now have an attractive water repellent sheen. What a pity this product is not more widely known in the UK.

    Excellent product & both deliveries arrived really quickly. We had a very faded brown pvc deck – which has come up beautifully and given it extra life. Really impressed – and the local decking company was so surprised we’d found a solution, they will probably be ringing you up too!

    I am very impressed with this product! I have to say I was a bit doubtful about the likely outcome when I read the reviews, having tried lots of other products from other manufacturers for restoring the colour to my faded GRP dingy hull, but this really is very good stuff! – I simply rubbed it in with a rolled up cloth – I gave it a couple of generous coats and rubbed it over with a polishing cloth before it completely dried (if it dried too quickly I just put some more on and buffed it up again). Some parts which had even faded almost to grey, are now a lovely rich purple (its an old Laser 2000) and it looks almost new. I may have to top it up a bit, but it’s so easy, I don’t mind at all.

    I am more than happy with Owatrol Polytrol, I am delighted. My garage door has now had two coats of Polytrol and looks as good as when it was fitted fifteen years ago. In the past fifteen years the door has never been treated with any other product and to get these results is just amazing, just wish I’d known about this product a few years ago!

    Just got round to reading the October issue of Practical Boat Owner Magazine. In it under ask the experts there is a question about reviving a faded gel coat. My trailer/sailer had a faded gel coat but rather than spend loads of time sanding down, I bought Owatrol Polytrol. You just rub it on and hey presto the faded gel coat comes back to life. Definitely worth the money – try it!
