I have one word... Halon. I used a dry chemical fire extinguisher once to put out a fire under the hood of my Dad's '61 Impala. The extinguisher did more damage than the fire. It destroyed everything aluminum. It all pitted like mad even though I cleaned the car within a few hours of putting the fire out. We eventually had to paint every surface that the stuff had landed on. What a nightmare!
