I just picked up a used stainless cylinder for a Ruger Old Army for very short money. While the chambers and nipple threads are OK, the exterior is lightly rusted and pitted.
I've already done as much mechanical rust removal on it as I'm willing to do. Now I'm looking for recommendations for how to chemically remove the remaining rust in the bottom of the pitting. I'd be grateful for any suggestions if such a thing is possible.
Thanks, Andy
