If you can live with the fact that you will expose large amounts of bare metal, meaning you will have to re-epoxy prime, you can go wild with the sanding blocks and sanders. I think, but can’t swear that I got all the dents address with glaze and primer. I did notice that the primer didn’t go on real even, wish I knew what was causing it. Came out dry at first then very wet, so it ran in spots. I was very careful to make sure it was evenly mixed, but maybe not? Had planned on following with filler primer but now I have to wait 18 to 24 hours to sand it, then filler prime. Spent a good 7 hours on it and get to do it again. Hope it goes better and faster because of todays work, fingers crossed.
