Brownells B.O.N. Crystals Bleed-Out Neutralizer 8 lb

Soaking the gun for 30 minutes in a 5% solution of B.O.N. and water (6 oz. to the gal.) between the cold and hot water rinse following bluing, will neutralize any residual salts and prevent this unsightly and damaging bleed-out - that white ring showing where barrel and frame join, around ribs, ramps or sights, and occasionally around milled-out sections in the receiver. Operates at 130deg to 150deg F. Use in regular type bluing tank. One gallon of mixed solution will do several guns. Can be carried over. Mfg: Brownells SPECS: 8 lb. (3.6kg) net weight.
