Sounds like you pretty have it figured out.

Black is a pretty good looking color but it sure does show the scratches and scraps. I would give that color a second thought.

The inside I went with gray Zolotone and it is a good color. Not to hard on the eyes when the sun shines and OK to clean. I would go with a few coats of clear there. Sure makes it easier for cleanup.

Have fun with the job and if you were thinking about doing a bottom coat of either Gluv-it or Coat-it I would do that part first.
