Spraying the inside of the doors, etc. All overspray is going to be sanded down next to do the final primer & paint spray with the doors closed.
The frame got a good coat of POR-15 to keep the rust away. Seems to be good stuff. A little goes a long way and soaks into hard to reach crevices. A bit of prep is involved with degreasers and acid etch spray, but sanding doesn't need to be perfect.

Blacking out the aluminum wheels and the chrome bumper. Painting aluminum, chrome, and plastic can have adhesion issues. After sanding everything down, I went over the aluminum with some POR metal prep (phosphoric acid). Then everything was wiped with acetone and then sprayed with some Bulldog Adhesion Promoter. Next a quality 2-part epoxy primer was applied and finally some Gillespie black enamel--flat for the bumper, semi-gloss for wheels. We'll see how it holds...
