I'll agree that the Robar products are simply outstanding. I had a Colt Officer's ACP finished in Roguard for the exterior surfaces and NP3 on all the internals. The pistol is carried regularly (amost every day) I've seen no evidence of holster wear or corrosion of any type, that's pretty admirable as in the summer months I sweat all over the gun. As I recall for Robar to finish the entire weapon was right at $200. I've also heard good things about Walter Birdsong's Black-T. I have a couple of Benchmade knives with the Black-T coating and it's heald up remarkably well considering the abuse I given them. Mark/FL
