I used some Casey's selenium cold bluing solution on my pistol, where I had done some grinding/polishing. I found it ridiculously quick and easy, and I didn't strictly wash the parts aferwards in water... is that a big oopsy?
Anyway, the real question I'm wondering about is: why should you not blue the inside of the barrel? I blued the crown, and instinctively stopped there, which I'm glad. Then I googled and found you should definitely NOT blue the inside of the barrel, but I haven't found out why. I am guessing it increases the friction?
