breakthrough adhesion question

Hi Guys,

after reading a couple of posts about breakthroughs i didn't get the info I'm after, so my question is If you're going up to 600 before paint and you break through to bare metal, will there be adhesion issues if you go straight to sealer since the bare metal will have such a fine/smooth scratch on it? The spots that I'm talking about are near edges, but not on them, and pretty small with the biggest being about dime sized.

OR should I give those spots a quick 80 grit and spot in 1:1 epoxy, then feather it in?
 
Bare edges and spots smaller than a quarter should be no problem, but lots of that might mean you really weren't done blocking. Any big bare metal area should be primed with 1:1, but don't get near it with 80 at this stage. Just clean it real good with waterborne w&g remover before spraying.
