High End Gun Coating Supplier Recommendations

[Sundodger]

Thinking of kicking off on a gun project where I would like to have the stainless steel action, bolt, and barrel coated with a PVD (Physical Vapor Deposition) like diamond like carbon (DLC) but might be willing to do melontite, or similar.

Not looking for ceracoat/duracoat/things that are paint/etc.

I have scoured locally (WA) and haven't found anyone so now I am willing to ship.

Any recommendations? I was recommended Club Customs, but when I contacted them it sounds like they are out of the PVD game

I have a couple that are Nitrided, I like it a lot, and I am having my next one done by @Unknown Munitions. They are close to Wa.- in N. Idaho.
