Novice body man here. I've done the sheet metal work and applied two coats of epoxy. I was hoping to wait a few days and apply 2k high build primer eliminating the need to sand the epoxy. However, I won't have finished the filler work by then. I've read you shouldn't apply filler over urethane primer. I assume SPI 2k High Build Primer is a urethane based product but don't know that for sure. So, is it a urethane and, if it isn't, can filler be applied over it?
