Unintended consequences...
If you want this try
Armoloy® .
I sent a Weatherby Varmintmaster action to these people for Armoloy finish .
They "vapour honned" the parts before plating including the locking surfaces .
The end result was a destroyed action with a $100 invoice.
There are NO gunsmiths involved .
Kenny Jarrett had a major problem when they plated the inside of match barrels years many ago.
Be warned!!
I have seen serious competition pistols done with Metalife finish on the other hand
that were perfect in finish and function.
Do a search on the pistol forums for the latest information.
