It depends on the condition of the vehicle. Since the metal was terribly beat up on this one, I sprayed 2 coats of epoxy on the media blasted metal first. Lightly block sanded to find the highs and lows, worked the metal with a hammer and dolly, skimmed the really rough spots with filler and then shot 2 coats of Polyester Primer.
From there I guide coat and block sand with 150 grit, which removes most of the Poly Primer and gets things fairly straight. Then I shoot 2 coats of 2k build primer over that and block sand with 180 grit until guide coat is removed and follow with 320 grit.
If all looks satisfactory I will wet sand with 600 grit and prep for paint.
