So here is what ive done removed 2 layers of Wallpaper hung directly to drywall with no primer = damaged drywall. I sanded drywall, primed, skim coated and then sanded. I honestly think I should have skipped the skim coat. Now I've painted. I used eggshell paint b/c HD said it would hide imperfections, and I wanted smooth surface so I got ultra smooth rollers. There are so many imperfections in the wall. I'm going to give another coat with a 1/2 inch nap. If this doesn't work what should I do? More skim coat?
