The 3M No Cleanup Replacement Nozzle is a convenient, easy-to-use accessory that is part of an entire system of 3M products designed to bolster and protect automotive coatings. With the help of the nozzle, operators can achieve clean, uniform coatings on automotive panels. Don't Stress the Mess Older coating systems required the coating to run through the gun, which meant operators had to disassemble the gun and thoroughly clean it. Now – because the coating is transmitted through the nozzle – the need for additional cleanup is eliminated. We recommend using this nozzle with the following 3M No Cleanup Coatings: - 3M No Cleanup Waterbased Undercoating - 3M No Cleanup Rocker Gard Coating - 3M No Cleanup High Coverage Body Schutz Coating Using the nozzle is easy. Simply insert the nozzle into the No Cleanup Can (sold separately) and press down until it snaps securely in place. Then, attach the nozzle to the applicator gun. When attaching the air hose to the gun, we recommended following directions and guidelines that accompany the Cleanup can. Modifying the pressure can change the texture and appearance of the coating. In fact, it's often a good idea to spray a small test panel and adjust the variables – air pressure, panel distance and number of coats – to figure out how to achieve the desired texture. Once the application is complete, simply discard the nozzle. It's that easy.
