OK, here's what I just used--and I'm real happy with the results.
Duplicolor auto spray Bordeaux red (you'll probably need 2-3 cans; they're small) for the helmet portion. It's got a nice deep red/crimson color and has a metallic sheen to it.
Krylon Short Cuts Gold Leaf for the faceplate.
I tested out several colors and these were the ones I liked the best. A lot of the paint jobs I've seen seem to have the helmet portion too red, but this was a nice compromise, and it being auto paint, it has a nice luster to it as well. The gold portion I wanted to have a metallic look, but not too shiny, and the Gold Leaf did this admirably.
I'll try to post pictures here in the next couple of days, but I hope this helps.
