Sorry, Here's some more pics.
I sanded etched primed the bare metal where the paint was going to be. Then primed over that.
The bottom is Steelflex over bare sanded metal, (based on Jerry's recommendation at Fasco).
Painted with Rustoleum and then put on a Clear Gloss Finish.
Overall, pretty happy with the paint job, being a first timer.
The Steelflex was a challeng as it sagged a lot. I think it might have been too cold(about 65-70degrees).
