Used to use JB every time I cleaned but now I use it only on new barrels like Gedubya and others and when prepping for a treatment of Dyna bore Coat. Just started using this and I think I will have less need of the JB after the treatment. Kroil is a good product but I make Ed's red by the gallon and add extra acetone to it if I need a penetrating oil. I use something else as a corrosion preventative. JB helped when I had a really stubborn shot gun to clean. It must have had layers or plastic and carbon like the rings of a red wood tree inside it even though it looked clean to the naked eye.

Kroil mixed with Shooters choice was the best around a while back, now there are several good products available. I use whatever is handy.
