It's occurring to me that during blocking of filler/2k over my epoxy, I will likely have break through to bare metal. I believe bare metal should have an 80 grit metal for the epoxy but the filler should have 180 or more. I can imagine a scenario in which I have blocked through my 2k and need to spot epoxy a small area that will have exposed filler, bare metal, epoxy, and even original paint. What grit would be best for prepping that whole area? Thanks!
