constant maintenance of weapons in the field to prevent corrosion by cleaning and oiling is extremely costly in man-hours and materials. The chemical blackening now used is at the outset. A form of rust and the alternative phosphating which is also currently used offers very minimal corrosion protection. Acid corrosion caused by detonation debris deposits are also a major problem. Corrosion caused by storage in damp, humid is a serious problem which is currently overcome by expensive oiling, greasing and packaging material. Gun-Kote SCK alleviates these problems.
