Car has to be sanded with 400-500 wet or 320 dry for most basecoat clearcoats. If using acrylic enamel you can sand with a courser grit. Thats final sand. Of course any bodywork areas will need a courser grit to do anything and will need primer and sanding working down to the final grit listed above. Don't leave any bare metal. You are going to want to get some epoxy primer on bare metal as soon as possible. Then later on the epoxy primer can be scuffed and if needed urethane primer sprayed on and body filler can be used over the epoxy primer.
