I paid $80.00, but I stripped the lock work out of the frame. If he had done that there would probably have been another hour, at least, bench labor charge. Colt internals don't scare me so it was the logical thing for me to do. My Colt is an "I" frame so the firing pin is in the frame, had to dismount the rear sight to get the firing pin retainer out, but that is just as well, I wanted the sight left original. I cleaned any over spray and then left it to cure for 8 weeks before I reassembled and tested. At room temperatures the Duracoat continues to cure for several months. It seems to be a workable finish, the pits are still visible but the rust and corrosion has been neutralized. It shoots like a new gun.
