Mike, almost everywhere, I went with just DP90 epoxy primer, which can end up with a maybe ~60% sheen when sprayed a little wet on a cool day. Big brother had painted the frame with Imron in the 80's, which is a super durable paint with high gloss...and it looked like hell, really, too thick and glossy and I took it off. DP90 is incredibly durable, it sticks like mad and protects wonderfully (I had patio furniture I painted in it alone and it lasted for years...).
I wish I could find something 'right' to replace the bitumen-infused felt along the front sides there, I finally went back with rubber sheet but I wish there was something more like the original (which is kind of a bitumen board). Bitumen felt seems to be easier to get in Europe, but pretty much all application for cars has otherwise shifted from less toxic asphalt. Metal and fiberglass is someone's later replacement, though it looks like the window frames for the asbestos are still there. I went with solid aluminum sheets there (instead of the open frames)--Lee
