[Healeys] Parkerizing

[BJ8 Healeys]

The danger of exposing high tensile strength steel to plating or pickling
solutions is that the hydrogen atoms in the acid solution will migrate to
the steel, causing embrittlement.  In industrial plating of high-strength
steel, the items are baked in an oven after plating according to a
particular time and temperature schedule to avoid hydrogen embrittlement.

I have no experience with Parkerizing, so I don't know if the process would
affect high-strength fasteners or not.

This will not adversely affect the strength of any fasteners.  Parkerizing
has been used in firearms manufacturing for over 100 years.  Barrels and
receivers are under considerable stress.  Parkerizing will not however last
forever if exposed to the elements.  It will look great and potentially
delay any rust, but if scratched or left uncoated it will rust.

Firearms are continuously oiled....   Ever seen an old cowboy or world war
gun?  They generally all exhibit some pitting / rust.

Parkerizing has been used by automotive manufacturers over the years, and if
done correctly can look VERY nice!

Absolutely experiment with it!  You'll want to Parkerize everything in your
house!!! :)

Good luck!
