Hi, Melissa. There should be no need to totally strip the door. First, fix the holes with Bondo. Mix according to the directions and slightly overfill the holes with a putty knife, pushing some of the Bondo down into the holes. Then sand the Bondo flush and sand the rest of the paint on the door featheredging any areas where paint is missing. Use 240 grit wet or dry probably for this and a sanding block where possible. Spray on a coat of automotive primer and lightly sand again. Vacuum and tack rag. Now you can paint with about any kind of paint you choose. If you can find a color and shine level at the auto parts supply house in a spray can that suits you, that will make it easy. But you can really use any kind of paint.
