What is the difference between epoxy primers and self-etching? I told my paint supply place what I wanted my primer to do, and he said I need a self-etching and a primer surfacer. The self-etching can go over bondo, but I can't put bondo over the self-etching. If the primer surfacer is 2k? (3 parts), what does the etching primer do? Also, I have another piece I used just the self-etching (didnt need surfacer) and I'm not sure if I can paint directly on top of it (it's been weeks).

Also, I'm about to spray clearcoat over my metallic paint. Anyone have any suggestions/tips on how to do it? I think I wait the flash time then spray the clear after spraying the paint. I was told by an Dupont rep. that I should then later buff the clear with a 3M yellow buffing pad. thank for any help!
