Blake, get a can of cheap spray paint (white primer-black paint) and give your primer a lite mist When you sand any little ding will still have paint and show up. Use a good two part filler followed by a two part spot filler feathering is out about two inches, don,t use a cheap single stage putty. Chean with prep wash, wax and grease remover has solvents which can be soak up in the filler and can cause problem later. I use a 2k urethane primer after that and 2k paint.
