How do you get the engraved/stampled letters and words on the receiver colored so that it doesn't come off with gun solvent/cleaner?
Specifically, I want to color
CAL 5.56 MM
and the fire control reads "FIRE" and "SAFE"
ON RIGHT SIDE:
MILITARY / GOVERNMENT
LAW ENFORCEMENT / EXPORT
Here's an similar example of what I'd like to do, but on a Bushy.
