Nice! What paint did you use for the wheel hubs? I tried Testors MM Acryl Silver before, but it was really thin/watery and wouldn't stick well.
I used regular acrylic from Testor, "flat Aluminum". You really have to mix that paint well to prevent it from thinning out. Apply two coats to get better results.
This looks AWESOME! If I had a way to and also the disposable income necessary, I'd send mine over and pay you to paint him up like that as well. Seriously impressive work!
