A Rivetting Paint Problem

[Stretch Cab]

Greetings, I'm working on finishing my grandfather's car project and while it isn't an "A" I thought you might be able to give me some ideas. As you can see the fender that I'm showing as an example of his body work is home made from aluminum with a hand rolled bead. The car has a lot of the beading and many rivets! My dad, grandpa's son in law remembers being very tired of bucking rivets back in the 60's when the car was built.
My question is, when I talk to a painter what type of paint would work best on this body with the multitude of rivets and yards of beading? I'm painting the chassis but will farm out the body.
What I've seen of base coat/clear, you have to color sand to get the mirror finish I would want and I don't see how to get around all those rivets. What would you do?
