Gelcoat Forum
Jim Willis, founder of Island Girl, has a gelcoat forum on this site. You can ask specific gelcoat questions there. I have yet to try his products but the great majority of folks here who have, love them. I've used FSR (Fiberglass Stain Remover) to mild success. It's basically just oxalic acid in gel form so you have to wear heavy duty protective gear and it doesn't really do much for the oxidation, just staining. Definitely NOT environmentally friendly!LaDonna
