Make a mixture of 50% Rustoleum paint, and 50% mineral spirits. The paint will be very, very thin.

If you over-apply the paint, it will run down the sides! Over-applying the paint will negate all the hard work you put into prepping the car for painting. If it happens, use a rag doused with pure mineral spirits to wipe off the runs.

Apply several thin coats of paint onto the car. Wait approximately 30 minutes between each coat to allow the paint to partially dry.

You will probably have to apply at least five thin coats of paint before the body (especially the Bondo areas) are no longer visible. Don't rush, and don't over-apply the paint.
