You can use any other urethane paints on top or underneath Auto-Air's for graphics. This also means that to clear the Sparklescent Rock Star Red, you can use any quality urethane clearcoat. Jerry uses PPG #4010 Hi-Solids clear. Once the last coat of color has been sprayed, you need to wait at least four hours in a booth with heat or at least 12 hours without heat on a warm day to clear the parts. Now is the time to spray heavy coats; three good ones should do it. Another bonus with Auto-Air's paints is that you can clear over them at anytime, unlike urethanes, which if you wait more than eight hours you would have to scuff them up for the clear to stick.
