what i used:
first time:
Bulldog Adheshion Promoter x1
SEM Flexible Primer x1-2
Paintscratch.com spray can x2-3
Paintscratch.com clearcoat x2-3 (think it was just Duplicolor Lacquer)
then i decided to change the color and paint more stuff
Bulldog Adhesion Promoter x1
SEM Flexible Primer x1-2
Sherwin Williams Ultra7000 System Automotive Paint x2-3
Sherwin Williams Ultra7000 System Clearcoat x3
unless you're gettin all fancy with a spray gun and air compressor and painting an evilina-quantity of parts, the paintscratch stuff was pretty nice
