Thanks foor the reply. I have had thoughts of being able to put the grey finish whatever the heck it is on some tools I own. I have a 2 1/2 inch S&W revolver custom made N-frame .45 ACP that also has a black Parkerized finish on it. I love the finish because of its toughness and rust protection.

Wikipedia gives a good overview of the phosphate conversion coating chemistry. Coloring depends on the type of phosphate, whether it is manganese, iron, or zinc. Manganese produces a black surface, and is probably the most used industrial phosphate conversion coating. An excellent finish for guns is spray and bake Teflon over a phosphated surface. Extremely tough and corrosion resistant, I have applied it to many guns. Commercial phosphating usually includes a post-application dip in a sodium dichromate bath which greatly improves corrosion resistance.
