I expect the thermal cycling does it no favorsI carried a can of SABRE pepper spray in the door pocket of my car. When it hit it’s expiration date, I discharged it with the wind at my back. It just sputtered and fizzled a bit. Maybe hot car storage reduces shelf life?
SABRE said:Do not leave your SABRE pepper spray in any area that may exceed 120° F or drop below 32° F . Excessive heat or cold may cause the can to leak or burst. Do not store your SABRE pepper spray in your car.
