Fiberglass cleaner is a mild-cut compound that removes film, light oxidation/discoloration/chalkiness, and tough stains from fiberglass boat finishes. Formula restores original color and gloss and facilitates the easy application of Collinite's last-step waxes to improve wax bond and spread/coverage and durability. Great for use on soiled fiberglass, gel coats, and lacquered paints on boats and RVs. Wax can also be used on tarnished chrome, stainless steel, aluminum, brass, and copper. Not recommended for coated/painted metals or clear-coat paint.
