Now here is a stupid question what is M/D. Thought the best thing to use was epoxy. Looks good. Like the shine. Russ.
It's called RustProof M/D by Martin Senour Paints, Link:

I thought epoxy primer too. I even have some SPi epoxy primer which is said to be really good stuff. But my autobody guy highly recommended RustProof M/D. Said he was not overly impressed with epoxy primer.
Anyway, what I like about Rust Proof is you can paint it directly over rust. And even though I sand blasted everything, I liked the sound of applying a product that could encapsulate and seal rust which perhaps we missed. Also, I am told it has great wicking properties that allows it to flow really well between panels and other tight areas. For example, the Martin Senour Rep told me you can paint it up to a strip of automotive grade, green, masking tape and the Rust Proof will flow half way under the tape. I was also told it will dry into a really tough glossy finish in which I can paint over or leave as a stand alone top coat finish. I also like that I can touch anything up with a paint brush if we missed anything after spraying like for example, behind the quarter glass panel and door jam area.
Anyway, I'm taking everyone's word for it so I hope it works out. So far so good.
