Great info, thanks guys. I hadn't planned on the EZ Sand step, I thought the high-build primer would take of the 80-grit scratches. Am I wrong to think this? If so, I'll do the EZ Sand. A little more info: I basically skim-coated the entire truck with filler. It had 50+ years work of little dings, dents and deep scratches in the metal. So between that, and all the little body mods I made (rounded the door corners, re-shaped the drip rails, pancaked the hood, etc), I skimmed the entire thing. So does "high build" primer fill 80-grit scratches? I've never used this stuff and am willing to learn. Thanks again guys, you guys are great!
