I have a 2.5 lb dry chemical in my Mach. I always dreaded the thought of having to use it, mainly for the damage they cause. I didn't know about Halotron. I think I'll replace the ABC one that I have with a Halotron unit.
Has anyone used, or carry a CO2 unit? Only drawback seems to be release time, which is less than ABC or Halotron. I'm also surprised that Halon is still available to the public. I thought it was banned, but turns out only the new manufacture of it is banned. Units are still available, albeit pricey. Still, seems like the best extinguisher available, and if it saves your car from burning to the ground, and not destroying all the aluminum and wiring in the process, it would be well worth the price.
Thanks for this thread, Alan. Having recently watched Tom Baileys Camaro burn, it put those fears of an engine fire back in my head.
