Generally agree with you Mike, but if you prep back to the primer should there be a problem with acrylic / 2 Pack combination?
The other thing with respraying panels to get that perfect finish you need to respray a whole panel or at least to a cut line (such as the stripes). I'll end up with half my car resprayed for just 3 dings!!!
Moral of the story - if dinging your car ding it in the same area!
