[AJD] metal coating

[Terry & Carolyn Welshans]

Mike, you might want to consider Parkerizing.  This is a coating that was
developed for military items that had to resist corrosion.  It uses
phosphate to leave a very thin protective layer.  Many WW2 rifles were
parkerized.  Here is a link to more about the process:
