I was wondering what the pepper spray guru's think about the expiration dates the manufacturers put on the cans and true loss of efficacy.
Specifically we have a bunch of Sabre Red and Blue Face units. I am probably going to replace all of the units that are out of date now, but I was wondering if it is out of date means highly likely to be less effective or if it leans in the direction of that is the approach the makers use to insure you are turning their product.
What really caused me to question this is the fact that the POM guys have no expiration date. They recommend replacement in 18-24 months but specifically state that is due to the likely damage to the case, not the deterioration of the contents.
