Great products and great customer service. I'm now using C4 and C2 for my rifles and Rim fire Blend for cleaning in of my 38 revolvers in which I shoot a lot of hard cast lead bullets. Hope they never get brought out or go out of business. Best products I've ever used for cleaning firearms. PS: I'm not a salesmen, employee or own any interests in the company. I;m just an old shooter who appreciates a product that exceeds expectations. Wife is happy too, always a good thing, since their products are odorless.
