When my barrel finally arrives it'll be plain stainless. I know people like Brownells' Aluma-Hyde and I've heard that it does stand up to solvents pretty well. I really don't need anything else from Brownells at the moment, and don't really want to pay $10 to ship a can of spray paint. Is there any other flat black paint you guys use that'll stand up to cleaning solvents that I can get locally?
