I have a friend that wants his carbon fiber bike frame painted and he's cheap. I told him I would shoot it with white epoxy while I was priming parts for my 69 firebird. Anyway, if we are going to have the epoxy as the top coat, what grit finish should the bare carbon fiber have so it is smooth and so the epoxy will stick? What about clear over the epoxy? I'm really worried about fisheyes because he started to sand the frame without degreasing first and they use all kinds of funky chain lubricants on those bikes. Thanks.
