Glenrock Blue was the first to come to mind for me. They do great work. Shipping could be a real hassle.Another is Glenrock Blue, in Glenrock,WY. They have a web site. Gun bluing is their only business. Shipping is possibly the problem. If you are not licensed and have a firearms account with FedEx or UPS, the USPS or "Ship My Gun" are about your only choices. As mentioned earlier in this thread by PopUNFresh, gun bluing is labor intensive, even if not going for that "Weatherby" gloss. Further, the chemicals have become expensive. I recently priced 125lbs, $625 I believe was the quote, with hazmat shipping required. Then there is neutralizing and disposing of the bluing solution. The mixed tank will last for a good long time, and chemical and water are regularly added. But, eventually, the tank will need to be cleaned and the mixture discarded. Your best bet is to source locally, if possible.
or put the camo tape back on and don't remove it.
