Marine Polytrol is a deep penetrating oil which restores the original color and appearance of dull or tarnished plastics, gelcoats, metals and other surfaces. It penetrates the surface, re-wetting the pigments to restore their luster and color 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 fiberglass (GRP). Marine Polytrol 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 Marine Polytrol 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

Restrictions

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

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

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.

Using Marine Polytrol on stone, brick, etc.

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

Using Marine 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 Marine Polytrol Color Restorer

General directions

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

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

Apply Marine 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 Marine Polytrol to stone, brick, etc.

Apply Marine 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 Marine Polytrol with a clean lint-free cloth. Leave it to dry.

Applying Marine Polytrol to metal

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

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

Maintenance

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

Clean Up

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

    This product works well. Goes on to full faded gelcoat and restores the color and sheen. Sometimes takes more than one coat but just wipes on… great stuff.

    I’m happy with the product. I goes on easy but can be tough to get off/polish. Not that difficult though. I used one clean towel for the first pass on removal, then a second clean towel for the final removal and it came out great. I would buy this product again.

    Does what it says. Brings back color without prior buffing and dries very glossy. Hopefully it will be durable.

    After 5 years of trying multiple different products from retail stores I was ready to spend hundreds of dollars to have the oxidation professionally removed from my 1983 Mastercraft gel coat. A friend recommended I try Gelcoat Restorer from Owatrol. Boy am I glad I did! Oxidation was lifted almost immediately upon application. After an very light buff out it looks brand new.

    Seems to work as advertised. Applies easily and did bring back depth of looks on metal flake finish on older bass boat. The shine is not glossy but more like a satin finish when looking at the top down the boat from the front. But the color in the metal flake is back. I am pleased with the results as other products I have used to try and accomplish this haves not done as well.
