BOTH PERMA BLUE® LIQUID GUN BLUE AND PASTE GUN BLUE PROVIDE GREAT BLUEING TO METAL THAT HAS ALREADY BEEN THOROUGHLY CLEANED AND IS FREE OF RUST. PERMA BLUE® PASTE GUN BLUE IS SLOWER TO DARKEN THAN LIQUID GUN BLUE, BUT WILL BUILD UP A DENSER FINISH. NOTE: PERMA BLUE® LIQUID GUN BLUE WILL NOT BLUE STAINLESS STEEL, ALUMINUM OR NON-FERROUS METALS.

• THE PROVEN WAY FOR TOUCHING UP OR COMPLETELY REBLUEING MOST GUNS
