From my understanding you don't need any "special" dyes, I'm not sure how it turns out, but I have heard of people using just ordinary clothes dies. You would have to try it out on a piece of scrap alluminum. What they also do is just use ordinary dish soap to clean the part, and boiling water to seal the part after it has been put into the dye. You also need some battery acid (sulphuric acid ???) and need to dilute it with water to a certain percentage, I forget what it was. Hope to be of some help. To tell you the truth, I have never anodized anything before, just researched some stuff on it.
