It's important to realize that extinguishers are a bit of a misnomer - their first, and really only priority is to knock the fire back enough to protect life (e.g. let you get out). If the fuel source is minimal enough that your little bottle can put it out then great, but in an avgas-fueled fire your chances of safely getting to the base of the fire are not great, especially in a closed engine cowl.
Training is critical. I watched someone try to put out a motorcycle fire at a racing event once; he didn't know how to work the thing (had seen them his whole life, but never actually used one) and ended up covering himself in dry powder instead of the bike. The race fuel made pretty quick work of that and it was only a pinhole leak.
I think a how-to made by a qualified person, with video showing how to aim and use a cockpit-appropriate extinguisher, would be a very valuable thing. Maybe show some ways hangar fires can develop as well. When I got my hangar it just happened to have a few extra extinguishers in there from the last tenant, so I distributed them around the space. Not much scares me in there except maybe a fire blocking my way to the man door while the big door is closed. Again, the point is to use them to get out. If I can keep the building from going up that's cool, but not my chief concern at that point.
On top of a video/article, practical experience is highly useful to have. Talk to your local fire station or airport, they may offer training or be able to help you out. Some employers will even sponsor it; mine had the local FD come out and do burn bucket training one day. The tendency to panic in a burning enclosed space is very real, it's a bad time to realize you have to read the instructions first.
I don't currently have one in my 182, but it's one of the first things coming to a cockpit near me once I get the interior reassembled. There isn't really room between the seats like the newer ones, but I'm sure some solution will present itself with proper application of power tools.
