Brenda, if you want to touch it up you might try Brownells 44/40.
www.brownells.com It's instant, and looks pretty good. I had a customer in today with a single action revolver that he'd been having problems with. It turned out that he had assembled the center pin catch backwards but there were about 40 little dings and scratches on the underside of his barrel where he had been tapping(?)the center pin with something. He asked if I could touch it up after I turned his catch around. I used the 44/40 on it and it blended well. It did not fill the dings however but they are now black. Customer left with a smile and a thank you. The stuff works. George
