I'm painting my 1992 6speed because the original paint had cracks and scratches. I'm taking a course at Southtech Academy in Boynton Beach for minor dent repair and refinishing. So I have air tools and a spray booth to use. I DA'd the whole car with 320 grit and sanded down to the plastic on the rear bumper cover and some other spots where the cracks were and bondoed any imperfections and sanded them down. I'm ready to paint next week and I have a couple of questions. My teacher said to sand it down with 320 grit, I've heard that I should sand it down with 400 grit. which grit is the right one?
My teacher said to use a sealer then base coat and then clear coat. Is this correct or should I also use a primer? Don't get me wrong my teacher is great at what he does, but he doesn't do much painting anymore, he just does body and frame work. Which is why I am looking for a second opinion.
