Our Bondo easy Finish aerosol trigger turns an aerosol spray can into a paint gun. Simply slip the trigger over the button of a conventional aerosol paint can for added convenience and control and for easier and more professional paint and coating application. Durable plastic handle is shaped to fit your hand for comfort. A safety lock prevents accidental spraying. For greater control and smoother application during auto body painting - without the added expense of a professional spray gun - our Bondo easy Finish aerosol trigger is simple, practical and economical. Designed to slip on quickly and snap cleanly over standard aerosol paint cans, it transforms the messy and inefficient vertical button operation of a can into the clean point-and-shoot flow of an auto body shop spray gun. The durable, easily cleanable plastic handle features a comfortable, natural design for an easy grip and nearly effortless trigger-pull operation. The safety lock is just as simple, allowing you to prevent accidental spray at any point during the process. The Bondo easy Finish aerosol trigger takes the pain out of applying paint from an aerosol spray can. It's another science-driven product from 3M , making auto body and collision repair faster, easier and more cost-efficient for professionals and do-it-yourselfers.
