I used Oxpho-Blue on the top of a Colt 1911 from 1953 where I had to plug holes from an aftermarket sight rail. The color matched well and it’s has stood up to lots of range time. Can’t really say how it wears since I don’t carry the gun but it hasn’t rubbed off from simple handling.
Yep, have used Oxpho before with nice results.

Yep, I should be o.k.
