Summit paint

bc/c base has a different binder which allows it to flash off quicker and even if you add hardener it is not the same as single stage. You can add clear over single stage as long as it is the proper clear - integrated urethane clear coat. This clear will allow the paint beneath to continue curing and will yield a slightly deeper and wetter look to the single stage. You cannot shoot regular B/CC over single stage that has not fully cured as you will end up with solvent pop (nice way of saying massive amounts bubbles) when the single stage beneath tries to gas off through the clear. You can, however, shoot b/cc clear coat over single urethane if it has fully cured. You will need to slightly wet sand (1000 to 1500 grit) and of course then clean off paint prior to shooting the clear.
