I use those plastic cleaning wheels that are diamond embedded for cleaning the old paint off. They work great and last a long time. Also make sure and use a grease and wax remover after cleaning it before you apply the primer. I use PREP-ALL from AUTOZONE for cleaning. Apply your primer with light coats to avoid runs. I persoanlly let it dry for about 30 minutes to an hour and then begin laying down my color. I've never sanded the primer on the ones that I have done and haven't had any problems. Also I use engine enamel for the lower units as it is a tougher paint, but it will fade pretty fast in the sunlight.
