Thanks for the following along, guys! I wish I could have brought this to the DSC, but next year I will...
Danno, that finish was a fortunate accident. I had sprayed it with Testors Aluminum Plate Metalizer and buffed it a little, but then I got a spot on it that wouldn't rub off. So I very gently tried to use some Blue Magic metal polish and it just lit up the finish, and since it was so dramatically different than than rest of the the finish that I had to do the whole thing. I didn't mind, because it really does look like real metal in person.
