I've done anodizing on parts for a paintball gun its tedious and messy, but anyone can do it. I will go to some paintball forums I frequent and find you ahow to if you want to build your own anodizing kit. I was just using 5 gallon buckets about half full, and I haven't tried anything but aluminum, so I don't know if it works for anything else. you are basicaly limited to what will fit in the bucket, but its pretty cool when it turns out good.
