Before you use it on a valuable gun...try it out on something like a scrap piece of rusty metal.....it messed up my gun big time when it scored the metal . I'm not joking...try it first .
I would send you the one I had but I tossed it after trying a coil wrapped around a bore brush for cleaning a barrel. Didn't like it for that either.
The stuff is way to coarse...razor wire is a great description of the stuff. Steel and bronze wool are a lot better.... in my experiences .
That baloney about it not scratching is doodly squat...
Those wire coils are NOT softer than bluing...
