paint question

I would wet sand the whole thing with 600 grit. I would then scuff the little nooks you missed or can't get into with sandpaper with a Scotchbrite pad. Blow it off, wipe it down with Final Clean, and tack it. Spray your light spots with color until covered, then shoot a coat of color over the whole thing, then clear it.

I agree, 1500 is way to fine. 800 grit is as far as I would finish before paint and that fine enough to put a shine on primer... scarey, lol
