At the moment I only have black dye. And have kind of hit an miss success with the aluminum anodizing. Haven't spent the time to sit down and sort it out. Plus it's like $30 for each batch or dye to make a couple gallons. So that's another reason why I haven't tried to do it. Most could do for faded parts with aluminum would be to fade from black to purple or something like that. Can't really do multiple colors across one part.
