Do I apply glazing putty before I prime? I have USG Icing. Is it good for rust pittig? Seems like Evercoat Rage Extreme would be overkill and the pits have DTM epoxy primer in them from the sandblast shop, and glazing putty sticks to primer, right? If you can't tell I've never done this before. I am sanding the putty with 80 grit, and I think I am supposed to glaze the sand scratches to prevent scratch swelling. Is that correct? Do I really need to apply 4 coats primer, block sand, and then 4 more coats?
