I was chosen by Stuff Stuff testing side of the North American Hunting Club to test this new product. :thumbup: :thumbup: After the major de-oiling with the supplied special cleaning solvent, treating the parts with the frog lube and heating it up with a hair blower, there was a little to wipe off. By this time the room your in smells like wintermint. With time at the range for testing after the treatment, my barrel of my pistol never did get dry like when treated with a well known oil. Treating the inside of your barrel also makes clean-up a snap, with no copper or lead fouling. A super product that I recommend to anyone wanting a superior oil that can be used on almost anything using a oil treatment.
