from 5 reviews
Gelcoat and surface restorer packaging
  • Restores the colour and appearance of dull and faded surfaces caused by exposure to sunlight, rain and pollution
  • Long lasting and penetrates deep into the gelcoat
  • Protects against corrosion and blemishes
  • Eliminates the need for waxes and polishes that sit on surfaces and dry out quickly
  • Suitable for use on fibreglass (GRP)

Gelcoat Restorer is a deep penetrating oil that penetrates deep into gelcoat to re-wet the pigment and so restore the dull, faded look of the gelcoat to its original colour and lustre. It then dries to a tough, long-lasting and flexible finish. Gelcoat Restorer eliminates the need for
expensive waxes and polishes that sit on the surface and dry out quickly.

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). Gelcoat Restorer dries to a tough and long-lasting flexible finish which does not leave a film – so it won’t peel or flake.

Ideal Uses for Gelcoat Restorer

  • 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, terracota, marble, slate, etc.
  • Reviving the color of faded GRP surfaces


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

Always read the Gelcoat Restorer 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.

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

Application of Gelcoat Restorer

General directions

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

First, saturate a soft cloth with Gelcoat Restorer and wipe it on. With a soft cloth, wipe off any excess within 10 minutes. Next gently polish with a lint-free cloth to a new sheen.

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

For application instructions for different uses of Gelcoat Restorer please see Polytrol.


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

Clean Up

Clean any tools used with white spirit. Gelcoat Restorer is non-flammable, however, any rags, steel wool etc. soaked in Gelcoat Restorer 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 Gelcoat Restorer to dry and create a film on the surface (always remove excess product).
  • Do not use Gelcoat Restorer on white surfaces.

    I used owatrol gel cost restorer on my 9 year old boat, the results were superb, incredibly easy to use and I now have a boat that looks like new. I think the secret is to wipe the owatrol off before it gets tacky. Very happy

    Applied to a test area as shown onto craftmaster painted steel barge, left for 12 minutes & wiped off, left a sticky matt residue which is worse than before, didnt appear to have soaked in at all, it was wet evenly all over start to finish.

      Hi Roy,

      We are sorry that you had a negative experience with our Gelcoat Restorer – we would like to help you get to the bottom of this problem.
      There are a few reasons as to why this may have happened; Was the surface cleaned before application? If so, please could I ask how it was cleaned? Also, how long was surface left before application of the Gelcoat Restorer?

      All the best,
      The Owatol Team

    Used on 10 year old fibreglass garage door and lasted for three years. Needs doing again though- not surprisingly. Would use again!

      Hi Neville,

      I am sorry to hear you had a bad experience using Gelcoat Restorer.
      It is most odd that it didn’t work for you – could I ask if you used it on a white surface? I only ask as Gelcoat restorer will not work on white surfaces.
      Could you please send an email k.coniam@owatroluk.com so we can discuss this matter further?

      All the best,

    Ok, here goes. I was sceptical to say the least, I wanted something that would bring faded gelcoat back to life. I have had several boats I’ve restored and been fortunate enough to be able to have them on my drive where I could sand them, cut them and polish them. My lastest boat, a river cruiser I did not have this luxury, I have had to work on it still moored on the river. This was the only product that promised to do what I wanted. The end result was it restored my gelcoat to a far better finish than I expected. It took my chalky blue finish to a more enriched blue. It was very easy to apply and went a very long way. You have to follow the the instructions, I left it on a bit to long and it went tacky. I will do a second coat and prob leave it about 5 mins. This is by far the easiest way I have found to significantly restore a boat with the minimal fuss and without taking it out of the water.
    Please note the warning on the can to wet your used cloths as they may combust don’t leave them on your boat or in your car. Put them in a bucket of water.
    This product did exactly what I wanted. It was a quick satisfactory fix to my faded gelcoat. I’d deffinatly use it again and save a lot of time in the process.
