Specially designed for the serious skeet and trap shooter. It neutralizes the corrosive acid residue built up from the plastic shot shells. Heavy duty solvents quickly remove leading, powder residue and metal fouling for a sparkling clean bore. Spray can ends loss of effectiveness due to evaporation of solvents and ends contamination due to dirty particles. Maybe harmful around painted metal, plastic, synthetic stocks or varnished stocks. It is recommended that the firearm be re-treated with G96 Gun Treatment, G96 Gun Oil or G96 Synthetic CLP Gun Oil after use.
