OK, what is a "bump"? Did it wipe off? Are you sure it was not there after anodizing? Do you have a 5% nitric acid dip between the anodize and the dye? Are you racked on titanium? What is the dye tank made of -stainless steel or plastic? What is the dye tank heated with
- stainless steel?
Try to give us some more information.
