I just got my Kimber TLE Rail II frame duracoated. Disassembled the gun myself, actually very easy. Only bummer is that the barrel nuts that hold the grips on are now cross threaded. Will have to find a tap/dye with the proper thread pitch as none of mine were the right one.
Came out beautifully in my opinion. We'll see how it holds up over time.
I'm thinking about doing the slide as well, but I'm a little apprehensive about removing the sights.
