after- if you thin and spray with a detail gun no sanding needed. if you use spray bomb it sometimes goes on a little grainy.

If you're going to HD buy the Rustoleum sandable primer. It's cheap (approx 3 bux a can) and it dries nice and level. Give it a light sanding after it dries, wipe it down, blow it off and you're good to go.
I buy it by the 6 can case!!

I wet sand my primer......sands nicely. 400 to 600 grit wetsand paper. I like it better than dry sanding. Just my .02

If you sand too fine the paint will have nothing to grab. I don't go any finer than 220 grit.
