The composition comprises powdered molybdenum disulfide suspended in a carrier comprising a volatile solvent and a binder selected from cellulosic-, alkyd- and acrylic-resins. Methods for the conditioning of firearm bores by the formation of a hardened layer comprising a product of the reaction or interaction of molybdenum disulfide with materials in the barrel bore are also disclosed.Other References
