This product is a mild cutting/polishing compound specifically formulated to restoring the outer (gel coat) finish on fibreglass boats. A fibreglass boat when left in the sun (unprotected by a cover) will slowly oxidise on the surface. This manifests itself as a faded ""chalky"" appearance. You apply this product in the same way that you would restore cars' paint. Use a dry cloth and rub, rub, rub.
