I finally got around to some paint testing; thanks to better weather. I used Tamiya fine light gray primer, topped with Rust-oleum 7718 Chrome, with a final coat of Dupli-Color Metalcast MC203 Green Anodized. I will clear coat it later to see what happens.
There was a bit of marblizingtoo the textur of the pice, I think I over coated the silver on one of the passes.
Here's one shot in the sun. More pix can be found in this album:
