There is still some small black pock marks here and there, I didn't want to keep grinding further for fear of not being left with any sheet metal... is it safe to primer and then paint over those areas, or do I have to treat it with a rust reformer first, like you did?
I have a loctite product that says that it can only be covered with oil based primer/paints, so I haven't used it yet until I find out if the primer I have is oil or water based.
