Polytrol is a deep penetrating oil that restores the original look of gelcoat, plastic, GRP, metal, and other surfaces. The oil re-wets the pigments restoring the lustre which has been lost due to exposure to sunlight, rain, and pollutants. Finish: Transparent Application: Clean the surface with warm water to remove dirt etc and dry. Apply with a brush or cloth and leave for 10 to 20 minutes. Wipe off excess with a clean lint-free cloth. On composite doors, Polytrol can be used on all colours except white. The effectiveness will depend upon the deterioration of the product, especially on stained doors where the lacquer coat has been removed.
