The process that we used to paint the car was 2 coats of Dupont CroMax Black Water Borne Base paint, then applied 3 coats of Dupont 8700 Clear Urethane. The clear coat Urethane was then wet sanded with 1500 grit sandpaper and then rewet sanded with 2000 grit sandpaper. We then used the 3M Perfect-It Paint Finishing System starting with the Rubbing compound and buffing to remove the sanding scratches, the next step was the machine polishing compound to remove the swirl marks and we finally used the swirl eliminator ultrafine polish which eliminates the very fine swirl marks and "presto a really shiny black paint job"
