RE: Fiberglass Cowl/Pin *****s
Trick I found with black is to change its color a bit to a lighter shade, or fog on a coat of flat before the final finish. That way scuffs won't show as bad. It also helps you to see if you have complete coverage. I'm inclined to agree with onewasp that the underlying problem is the release agent. Used to find the same problem on full scale boat hulls. Tough to have to remove the primer you already applied but we build for fun and to pass the time. This will help in the time passing department but only delay your first flight for one day.
