Crenwedge, at least some things have gotten better. I get primer from my Son's bodyshop. It is unreal how it covers sand marks and imperfections. He uses a 3-part primer. It's a primer-reducer-hardener mix.
You can wet sand/block it once, then spray another coat and block/sand with 500 grit. Then you have a super smooth surface to paint on.
(But it is expensive stuff)
