The gray phosphate/nitrate coating sounds like Parkerizing.
(https://en.wikipedia.org/wiki/Parkerizing)

Gun parts places have home kits for doing the same (such as Brownell's
http://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/parkerizing/benchtop-parkerizing-kit-prod22737.aspx)

But there are other coatings that might be easier to use such as
Cerakote

or even easier might be Duracoat
(http://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/paint-finishes/air-cure-non-aerosol-paints/duracoat-paints-prod44374.aspx)

I haven't seen the coating you're talking about so I could be way off
base too...
