I don't think I would put anything with tree sap or resins in my gun barrel. Bear grease, and venison, or mutton tallow, is what I use, and haven't found anything better. Some of this exotic/oddball patch lube is flat out dangerous in hot dry climates. The flash point of some of this stuff is way too close to a low grade propellant for comfort. Fighting fire with a powder horn around my neck is not my idea of fun. just sayin'.
