Second, in the late '80's a former co-worker was going to get into the fiberglass body business. He bought a nice chopper gun setup, had his molds made, etc. His story was that it was a cold day, so he was using some extra hardener to help the glass set up quicker. As he was cleaning the equipment with acetone, the hot resin started a fire, and he was luck to excape with his life.
Fiberglass will catch on fire if you lay it on too thick with a lot of catlyst. The reaction creates heat and if you layer it on really thick it will go up in flames. Someone I know almost set their work on fire. He said the best he could do was pour water over it after it started smoking.
I second the mythbusters. I have my doubts on how easy it is to get a perfectly concentrated mixture in an area large enough to be combustible. Like you I have never heard of any stories of explosions with car painting.
