Woodcraft makes a purple dye just for doing purpleheart. I have used it with good results. It was exactly the same color as the fresh cut wood. Just let it dry overnight and topcoat to suit.Bill, what did you finish coat with after armoralling the padauk? I have a couple of 8 x 6's of padauk and purpleheart I've been saving to do amp chassis' with. I made a heaphone rack out of purpleheart and padauk where I dyed the purpleheart, but left the padauk alone and finshed with about 8 coats of Formby's Tung Oil.
