B - The LMF really is easy to work with. It gives a satin finish, not shiny, if used per the directions, i.e. it gives a stronger etch than some.
Thanks Judge. I'll give it a try next go-round. I've got some dents to remove from a 20ga Sterlingworth (Savage re-barrelled) barrel, and then I'm ready to with my first rust blue undertaking.
If it turns out well, then my plan is to give it to my wife. She hasn't exactly asked for her own shotgun, but maybe she'll like it anyway and come out shooting clays with me.
