Do you know what type of system (mechanics) they are using for the flat fix?
We'll know for sure soon enough, but it is my understanding from one of my contacts that it is basically a non-pressurized container of fix-a-flat, coupled with a built-in pump that plugs in your 12V recepticle. If you get a flat, you pull this thing out, screw it into your valve stem, plug it in and wait for it to pump the goop in and inflate the tire. There might be some issue with driving it (like the manual glop-in system that the SSR, C5 Z06, and RX-8 have - those systems you have to remove the valve stem, and squirt the goop in manually). Driving it after the goop is pumped in distributes it in the tire and seals the hole, after which you can plug this thing back on and pump up the tire.
Reason they use that is it is not possible to guarantee the integrity of a pressurized canister (like you buy at the store) for the life of a car against moisture and condensation/corrosion, nor the temperature fluctuations that a car may see throughout it's lifetime. Most of your store-bought pressurized cans of fix-o-flat say right on them not to exceed 120 deg F - and the interior of a car can exceed that under the right conditions. Also the propellant in those systems is usually butane (so a word of caution for folks who carry a can around in your car - you've got a can of butane and semi-flammable rubber-based goop in a can under pressure. Be careful and replace it every year, if you know what's good for you

).
That's what I've been able to piece together from multiple sources, but who knows, they may change back to the Corvette/SSR/RX-8 system for all I know. I'm quite sure, given the explanation above, that it is NOT a pressurized aerosol canister like you buy at an auto parts store.
