Valve mod - pcp pistol

Heating up a barrel to red hot+ and quenching it in oil is how you harden metal. It would also present the problem of being able to block the barrel so the bluing didn't take effect inside.
Then theres the whole warping of the barrel issue.
The way to bring the metal back after hardening is to bring it back up to heat and cool it slowly.
Having worked around die casting, and needing a durable coating on the products after wards, powder coating was used.
This required a bath in various cleaning chemicals, then the metal objects were hung with a low voltage running through them sprayed with the coating power. The static charge allows the powder to adhere to the metal in an even thickness. After that it is baked on at much lower temperature.
It would also allow the barrel to be blocked with something as simple as a plug while spraying and removed for baking.
Its a durable coating and unlike bluing isn't reactive to hand sweat.
A single object can be done along side production objects with no extra set up needed.
I don't know why it is not used.
Colour options are as varied as paint.
It could be an alternative to blueing.
