I just bought a project boat that I hoped to just buff the gel coat but looks like I’m going to have to redo it from the rail down to the first body line. I hope someone has experience with this that can keep me straight. I restored a boat a while back but opted to paint with a polyurethane and it was beautiful but I really feel paint kills the value of the boat. I understand the process for filling all the scratches and gouges to get it slick but I’m interested if someone knows what grit to prep for spraying and then process for blocking and buffing. I know this is a paint forum but usually one of you guys has some experience to pass on for just about anything. If anyone cares it’s a Cape Horn 21’ offshore boat. Just solid white.
