Is there a chemical stripper that can remove gelcoat down to glass? I am doing a total restore and want to get it down to glass as much as possible. Does anyone know of any strippers that could save me some work?
I really do not think there is anything to do that. anything that would attack the chemical make up of gel coat I would think would also attack the resin in the fiberglass. Do you plan of spraying gel coat back. I do not know how bad your project hull is but sanding it smooth will do just as good as taking it all the way off. I am working a project hull myself and I did sand to the glass in a few places where the stress cracks were really bad. I also sanded and filled a lot of cracks with 3m premium filler. I am going to spray awl grip but the prep as far as how much to remove should be about the same.
This boat has been stored outside in louisiana and I am afraid mildew has set in into the primer. I am probably going to re shoot gelcoat. Right now I am only going to take it down to glass in the really bad looking spots. I am then going to give it a good bleach bath and hope for the best.
