MFR # K9-1oz/1.5ozUPC: 736211152077FrogLube is a heavy specific gravity "food grade" mixture that seeps deep into the micro spaces of the metal and acts as if to 'season' the surface of the bore, any friction points and all areas treated with the lube. Once treated, fouling particles resist bonding to metal surfaces; instead, they easily wipe away or brush off the surface. This also applies to other loose fouling particles such as dirt, dust and sand. FrogLube does not film, nor is it a coating. Instead it is a treatment that is absorbed throughout the firearm. It is water insoluble and will repel water and resist corrosion.
