He didn't really get much more than a paint job, but it came out really nice, I mixed blues, black and white, and added a little metalic silver dust. I hand painted the stripes back on using a red and grey. Also his details were with some crazy paint we got in this little store where we live pewter and bronze. We gave him Ultron hands that just plug into the cannons perfectly.
He also got a gun made from various pieces that were laying around.
