Designed to fit most aerosol cans, you’ll be able to use the 3M Paint Defender Spray Trigger for most of your painting projects. The 3M Paint Guard Spray Trigger makes protecting your vehicle's paint even easier. Simply attach the trigger to the top of the 3M paint guard spray film aerosol can for a clean, uniform application.
