This is for my 96 z28. The paint on the hood has really gone to crap over the last year since I bought it (aftermarket hood --> bad paint job). it has hood pins also which i plan to remove and fill. can someone run me through the process for repainting this thing right myself? it is fiberglass...should i sand it down bare or just scuff it real good? what grit do i want to use? it is being painted the same color, but i am also painting a spoiler which is a different color...do i want to take any other steps to prep that since it is a color change?
