First time I ever had to use a fire extinguisher for something that would have gotten out of hand was just about a week ago..Emptied this white one I had in my frunk on a friends older but mint 3.0 Acura After using some brake cleaner on a cold motor. It got into a sealed electrical connector and ignited a fireball about the size of a beach ball under the hood soon as he started it up. I had a water hose on laying near from watering plants and grabbed it then remembered the Chem one in my frunk
