actually, if the kit has already been painted b4, you shouldn't have to worry so much about primer. just sand it down to a roughness with about a 180 or 80 grit paper. get all the imperfections out(chipped paint, scratches, etc) then u can just put the new color over the old once it's all smooth. i work at a body shop where the guy's specialty is crotch rockets, and a big percentage of their body is fiberglass. hope this helps
