i had spray can painted a mould, to close up the pores from sanding down … after it dried for several days, i waxed it and used white gelcoat to start laying fiberglass… and i noticed the gelcoat which was white was getting a red tint from the paint… that look bad… anyway i dropped another layer of gelcoat tonight, and im gonna continue tomorrow with FG, cause i had no time. you guys think it will demould fine, or we will have a nuclear reaction on our hands?
