B'laster aerosol products have a shelf life of three years from the date of manufacture, during which we offer a warranty for cans that fail to dispense as designed. 

The date of manufacture is found either etched into the paint toward the top of the label (approximately ½” below the bottom of the cap) or printed on the bottom of the can. It follows the YYJJJ format (the first two digits are the last two digits of the year and the next three digits are the day of the year. 16041, for example, would be the 41st day of 2016).
