Thanks!
I meant that I need to delve deeper into its micro structure. I have to know quite a bit about anodizing and plating for work, but I'm lacking when it comes to parkerizing.
Here is my current setup. I''ve done one zinc test part, then went on to a few others where the intent is to turn the parts green. The owner of palmettoenterprisesparkerizing told me to take WWII era cosmo (they have since changed formulation) and slather the parts as soon as they dry coming out of the bath. Then wrap tightly with aluminum foil. The parts will be unwrapped in a week.
The basic grey color matches a buddy's 1911 he got from his grandfather. Grandfather was a Korean War era MP who purchased his duty pistol after service. But it was shipped at a later date (he has the box too...). The pistol's finish is immaculate. Methinks that it was shipped later because he requested it to be refinished and they skipped the chromate bath. I know that there are two lines of thought as to why the park turns green, some people saying cosmo, others the chromate treatment. Ok, enough digression....

Park
SA hated Parkerizing, fought it tooth and nail because it increased friction and changed the dimensions. They found Pentrate, a bluing process, and tried hard to get it accepted instead of Park. In January 1939 they build 10 rifles in the 7000 serial range and sent them to Washington. Ordnance rejected them as too shiny. They made a second lot of 25 in April (12000 range) after frosting the parts with muriatic acid to dull the finish but Ordnance rejected that too. Ord loved the superior rust resistance of Park and finally told SA to shut up and step out smartly. It's one of the very few times SA lost a fight until the M1C/M1D controversy.

Green tint
Tried for years trying to get a green tint to my park metal. Here a couple of pics of my results.

I don't know why everyone worries so much about it, if you have a nice clean grey or black finish and the rifle looks in almost new condition, it'll be a working showpiece.
That's about the best you can ask for.
