  • Available in 0.5L (0.53 US quart)
  • Restores the color 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

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 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.

Ideal Uses for Polytrol Color 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 color of faded garage doors


DO NOT use Polytrol on white surfaces, it will not work as Polytrol 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 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 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 Polytrol unevenly (i.e. some matte and some shiny patches) move any surplus oil from shiny areas to matte 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.

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 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 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.

    Product did a fantastic job restoring our Sport Court. After 18 years in direct sunlight the court finally needed a face lift. We where quoted $6500.00 to refinish the tiles hence the reason we searched and found this product.
    16 cans 2 rollers and beautiful weather is all it took to make our court look great!

    This is a great product, I used it on my garage doors and on the vinyl fence. It brought out the colors beautifully and made them appear as new. I hope it lasts years to come.

    Didn’t work on my front door at all. Have a faded composite door. After 5 coats no change to the color of the door. Sent a picture to the tech team and all they said was the door was too faded to restore. The door is barely faded. Don’t waste your money.

      We are sorry that you have had a negative experience using Polytrol. If the door had some sort of clear coat (normally anti-uv) applied over the top of the colored composite at the time of manufacture then the Polytrol cannot get to the pigments as the clear coat is stopping the Polytrol from penetrating. 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. A tip is to pour half a cup of water over the faded areas. If the color shows back while still wet then Polytrol will work, if not then the door is to faded and Polytrol will not work.

    Love, Love, Love! So easy and great results! After many rainy days we finally were able to prep the doors and apply Polytrol . It went on so quickly and effortlessly it was surprising. All my family and friends are sold on it- all it has to do it hold up for a reasonable amount of time . They all want my feedback. Keeping my fingers crossed.

    Tried lots of different products to revive a very faded 8 year old black composite front door.
    I was sceptical as I always am about online reviews, but this stuff really does do the job!
    Plenty in the tub, probably used about 1/8 of it on the door as I lashed it on.
    All together took about an hour or so. Hopefully it’ll last a while before needing to be done again but the time took I’d gladly use it every 6 months if needed

    This is a good product.
    The product was easy to use and made a very noticeable difference in the way the plastic tile that I applied to looked.
