This Undercoating Gun distinguishes itself by offering the most adjustable nozzle in the industry. Screw the nozzle inwards to restrict the product flow allowing only a fine mist to be sprayed. Adjusting the nozzle outwards will increase the product flow and create a more pronounced textured finish. It also features a solvent resistant vinyl tank connector, aluminum tank and body designed to spray undercoating and rustproofing liquids. Can be equipped with an optional undercoating wand to spray in areas that are difficult to reach, ie; around mufflers and exhaust pipes. This gun is NOT designed to spray motor oil or paints. Do NOT disassemble gun for cleaning. Cleaning instructions included with gun.
