Dick,
I think the guy should have offered to re-fill your fire extinguisher for you at the very least! This makes me thinl that I might just buy a Halon extinguisher to use on a fire in MY CAR, and keep the chemical one I currently have for a "rescue" bottle
like yours!!
Sorry about your burn, but welcome to the "Snakebite Club". Follow Drew's lead and get the ointment.
You REALLY had a TCC meeting to remember!!
