As more input form someone who works in a collision shop (body shop) me. Always use wax and grease remover before you paint anything or primer sealer for that matter not primer filler. And for raw plastic parts like our plastic side moldings use a special sponge for RAW plastics and when ready for primer sealer use wax and grease remover then apply a special wipe for RAW plastics to help for adhesion. And use a tack rag after you paint but before the clear coat.
