If you know anything about polishing guns, you know how easy it is to "dish out" screw holes the roll marks. Care and the proper tools must be used.
These guys are absolute pros, the best, they also do nickel and gold platting.
Anyway, I contacted the owner and he agreed to let me post some of their work here for you guys to gander at.
