Paint Defender Spray Trigger makes uniform, clean application of the 3M Paint Defender Spray Film, PN 90000 even easier. Designed to reduce hand and/or finger fatigue associated with aerosol cans and small triggers, this device features a comfortable grip that allows you to use your entire hand, instead of just one finger, to apply pressure to the trigger. By applying even more pressure, you will minimize the risk of uneven spray application, saving you time on your project.
