DC, I'd like to address one thing, and if you don't mind, I may repost this thread in another as a PSA. When we carry a dry chemical fire extinguisher in our vehicles for a prolonged time, the powder will compact in the bottom of the extinguisher. It's quite simply due to the bumps and bangs it receives as we drive. It's widely recommended that once every couple months or so you remove the extinguisher from it's mount, turn it upside down and rap the sides sharply with a rubber hammer. Remember folks, a rubber hammer, not a dead blow hammer, they're different and in this case, not interchangeable. You should, if successful, be able to feel the powder shifting as you turn the extinguisher right side up and upside down.

I thought that was the case at first, but it seems that all of the propellant had seeped out over time! Not an ounce of CO2 pressure to even puff the dry powder once! There was not a pressure gauge on the bottle, so I never knew.
It is probably a good idea to agitate the extinguisher every now and then. I think I will go with an all CO2 replacement - one with a pressure gauge.
