i have a 1990 formula front nose cover im putting on my 1986 firebird. it is in need of some filling/paint. there is a gouge about 2" long i must fill and im wondering what to fill it with. also, how should i strip the paint off the bumper and how should i prep the surface before priming it and what i should wet sand the primer with before i have it sprayed. and what is the factory color code or whatever for the bright red 1986 Firebird as in this pic 1986 Pontiac Firebird - scott's Pontiac
