Dicropan T-4A(R) - Dicropan T-4 Touch-Up Liquid Gun Blue 4oz

T-4 is in the catalog because of customer demand. As Maynard Buehler said: "THIS is the BEST yet." Every time a new gun blue comes on the market, we test it on a piece of gun barrel. We blue three spots: one with the new blue, one with Oxpho- Blue(TM) and one with T-4. One day later we start rubbing all three areas with steel wool until one of them starts wearing off. So far, Oxpho Blue(TM) is toughest and T-4 next. However, for ease of application and deep density of color, T-4 is superior. Its ability to touch-up wear areas and scratches instantly has made it a favorite. Mfg: Brownells SPECS: 4 oz. (118.2ml) or 32 oz. (.946L).
