Brett, you have too much time on your hand, but I admire the work that comes out of it.
I’m pretty sure he paints it, but yes you can dye metal. It just takes a lot of electricity, but that is exactly what anodization is.
Okay, okay I’ll try to clear it up. Anodization is a way of “Dyeing” aluminum. You can use a regular RIT dye even, but there is a catch. Metal is pretty stubborn, and it wont just take a dye. What you have to do, is set up a complicated rig (that I won’t go into detail about here) that basically uses electricity to make a bunch of microscopic holes in the metal that will “hold” the dye. Sorry for any confusion.
