Willcox or Zip or Corvette America should have the dye. Don't use paint, it will cover up the grain and dye is easier to work with. Autozone has a few types of dye but it is crap. Some people prefer SEM, not sure where to get that though.
The Corvette America spray dye (sold by Willcox) is great. Consistent color. Dries super fast (can handle in 2 minutes) if you spray a light coat (that is the way to do it). It does a good job of bonding to the part (if clean and/or prepped), does not peel, and does not mask the grain.
