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.

    Like Steve, I wasn’t sure this could possibly do the job, but thought I’d give it a go as the alternative was to pay £1000 for a new door. So glad I did, it is very easy to apply, it just wipes on and dries leaving a luscious colour restored glowing surface which looks like new. I took one photo part way through the exercise, and you can see the difference between the untreated panels and the rest of the door….brilliant product!

    Magic in a can, sceptal at first, after having a quote of £1200 for a new door, this is worth a try, wow, it looks like a new door, inspired by result’s decided to take on a much bigger challenge, the Static Caravan, like us all faded with age, again results unbelievable, the comments from “ that must have taken some sweat and tears to make that shine , to
    Where did you get that from “

    Excellent product. I give my GRP garage door a coat once every couple of years and it brings it up like new. Very easy to apply and goes a long way. Super fast delivery.

    Purchased this to try and restore badly faded grey bumpers on 2015 UK Ford Ecosport vehicle.
    Have tried numerous products over time without success until i came across this particular car bumper and trim restorer product.
    Had to wait for a dullish warm day before carrying out my work as not recommended to apply this product in direct sunshine!!
    Firstly gave my car a good clean with well known brand snowfoam by BH.
    Allowed foam to dwell for 5 mins then power washed off then allowed car to dry,
    Cleaned all the grey bumpers and trim with an isopopryl cleaning agent and allowed to fully dry.
    Then finished by pouring small amount of Polytrol into a container and applying the Polytrol very sparingly with a small brush and then cleaned off excess quickly with a lint free cloth as per instructions.

    Absolutely blown away with this Car Trim Restorer product.
    My only gripe was product was expensive for the
    0.5 litre purchased but well impressed with this product.
    Highly recommend this product.
    A Very Happy Scotsman
    Bumpers hand trim have come up brilliantly and look like new bumpers and trim on car.
    Absoluterly gobsmacked by the difference in appearance of car.

    I have a Thule roof box that has had a lot of exposure to the Aussie sun. It came up a treat as you can see from the before and after shots.

    I stupidly wiped my door over with a surface cleaning product that contained something harsh and it lifted the surface colour. I stopped as soon as I realised ( this was quite a while ago).
    Absolutely flabbergasted with how this has transformed our front door. So easy to use and the results make it look like a brand new door.
