Gillis uses SPI products exclusively, so your paint's manufacturer may require different dry times or flash points. That being said, Gillis started with the car in SPI black epoxy primer, and the body panels off of the car. With the SPI epoxy, you have seven days to paint before you have to sand and spray another coat. Once the bodywork was complete and the car was in epoxy primer, Gillis started wet-sanding with 400-grit paper (400 for solid colors and 600 for metallics) to remove any imperfections. He then wiped the car down with wax and grease remover and a tack cloth.
