I am thinking of sending a stainless gun to Robar for the NP3 on the internals. Their Roguard would be an excellent exterior finish, but to save some money I was thinking of coating/painting it myself. I really don't need the external finished, I was just thinking a drab color would be best.

Anyone try Dura-Coat? My research seems to indicate it is the best DIY paint/finish, especially since I have the air equipment already. I have heard horror stories about teflon finishes not wearing worth a darn. The moly-sulfide coatings are probably best, but a bit pricey to get applied.

Seriously considering good ole rustolem too in combination with my current method (car wax)

MetalMan - spend your hard earned money with Robar, they will do your firearm right - JMHO - KMule

Mac's shooting irons does a KG finish. He returns emails quickly. Turn around is 2 weeks. He will do a barreled receiver all metal (except springs)including the sling studs and swivels for $190.00. Less if you do some of the tear down. This includes lapping of all parts for fit and function. He has a website. Gun is bead blasted and parkerized before the KG is put on. Iffen you mess it up, run or a fish eye or something you have to abbrasive blast it off.
