Refinishing a pre '64 Winchester 94. I know the nickel steel may be part of the problem, but it doesn't seem likely due to results. Barrel came out flawless, receiver is the problem. It is now nicely blued, but has streak that I can't get rid of. I had it totally blued once, but, because of streaks, I resanded and started over. I'm now at the same point. For information, I am degreasing with denatured alcohol after each carding. I am using Laurel Mountain Barrel Brown solution. I will mention that this is not my first attempt at rust bluing, as I have done at least 50 mixed rifles, shotguns, and handguns by this method. It is driving me crazy, so any suggestions will be greatly appreciated.
