I think my mistake was doing it in my cold basement. Doesn’t matter at this time Im probably going to wait until July to try again. I have repeated my self several times stating the barrel was not rubbed touching the damp cotton patch instantly brought out the copper yet i keep being told I rubbed it my barrel was wet lol! I appreciate everyones comments and I have the expanded instructions with the one liner about rubbing will cause a copper effect. Funny they don’t follow that with a remedy. I kept applying as others have recommended and those areas blacked rather than rust. The rust actually didn’t look bad after the second treatment and moved it to a warmer area. But the black areas didn’t do well when carded the touch hole not the plug itself but the perimeter maybe a 1/16 or two wide surrounds the touch holes. Typically you get everything brow and a nice sharp touch hole. This could only happen to me and this gun that I started over a year ago that I put aside for 6 months to keep it out of the wood stove. Maple burns hot and fast. LoL. Sorry for being a crab I’m kind of fed up with this rifle.
