Now, in one easy-to-use and inexpensive kit, everything needed to start a gun bluing business! It is a great and affordable process that will provide a highly desired deep blue finish. This complete system includes everything but the gas tank and contains enough materials to do up to 100 long guns. System includes: Set-up and operating instructions, plus material safety data sheets (MSDS). Safety equipment: One pair of plating gloves, apron, goggles and six dust masks. Four bluing tanks. Tanks are 14-gauge steel and are 6" x 9" x 40". One tank is used as a cleaner tank, one as a black oxide tank and two as water rinse tanks. One solid, angle-iron tank stand holds all four tanks and eliminates the danger of tipping. Two 39,000 BTU/HR gas burners for the cleaner and black oxide tanks. System comes complete with air mixers and shutoff valves. Gas tanks not included. One stainless steel dial-type bluing thermometer. 50 lbs of Du-Lite Steelkote (bluing salts). 10 lbs of Du-Lite #45 cleaner (removes grease, oil and buffing compound). One gallon of Du-Lite Kwikseal (water-displacing oil). Additional chemicals should be ordered directly from Du-Lite.
