Default Dimple After

I use Akzo primer and I dimple after priming. I've had no problems at all with the dimpling process damaging the primer.
Everyone has their own preference here, but there's a couple of reasons I prefer to dimple after priming. First, it is much easier to prep your parts (especially if scuffing with scotchbrite adds) without all the dimples. Second, and this is my own silly reasoning, is that if you prime after dimpling you may, very slightly, (fill in) the dimple with primer. Dimpling after gives you a nice full dimple.

Btw. My prep process is scuff with maroon scotchbrite pad and prekote.

For me its:
  • Maroon Scotchbrite and Bon-ami
  • Rinse thoroughly
  • Wipe down with denatured alcohol (acetone leaves a residue)
  • Primer goes on within 2 hours of scuffing
  • Dimpling after primer dries (using EcoPoxy). I've absolutely no issues dimpling after priming.

+1, I've been dimpling after priming and it holds just fine - just respect the cure time (personally I give it 48h after applying primer before doing anything, may be possible with less but I haven't tried). I'm also careful to not apply primer if relative humidity is higher than their specified limit - the one time I did it over the limit, I got bubbles and it didn't hold as well.
