Hey, all. The body is off for its last time. I hope to start primer in a few weeks. Now that the body is off and weather will be good nex week, I'd like to spray the Raptor liner kit I got late last year. What prep should I do to the fiberglass underneath? I found one old post that said to go over it with 80 grit and degrease, but that is about all I found easily.

Thanks for any suggestions,
Mark
