The Kimber that I use for USPSA matches was starting to show a considerable amount of wear on the slide which was ok, but corrosion was becoming an issue because the slide is carbon steel. The stainless steel frame was holding up just fine, but a couple of months ago I shipped it off to Dave Severns of Severns Custom to have him treat it to his "Hard Hat" process. The price includes two magazines and the barrel if you wish. I sent him a pair of Kimber stainless and carbon steel 7-round magazines and asked him not to treat the barrel. When I got the pistol back I was happy that he forgot about my request because the pistol looks really sharp with a black barrel. The inside of the barrel is black too. While it was with him I also had him install a set of Heinie straight eight sights. I'm not sure how well this finish will hold up but I'm sure it's better than Cerakote, GUN-KOTE or the factory finish based on the anecdote on SC's website.
This is how the Kimber looked before the "Hard Hat" finish.
