Titanium nitride seems to be all the rage for racegun accents and glock barrels, but not in many other circles. Has anyone tried applying it to MIM parts?

Kuhnhausen complains about MIMs susceptibility to corrosion, and that is often one of the selling points of TiN, and given that its fairly cheap, I am surprised I haven't seen it pop up on any S&W guns.

Of course its gaudy hell but hey, if its smoother, harder, and more resistant to the elements... I figured someone would give it a try.
