Just noticed that I have rust on my 1858 after only one use. I spent half an hour cleaning it, too. The rust isn't located anywhere vital, but I don't like seeing it already. The only thing I can think of is I left a little too much bore gel on afterward, because the rust is located where there was no open air contact (between the front of the cylinder on the steel frame, and behind the cylinder in the middle of the nipples). I'm going to try to remove it with Hoppe's No. 9 type liquid and a bristle brush. Any thoughts?
