Mine never caught fire but the stink is undescribable when synthetic spills
on it and it smolders for weeks. It wasn't a consideration when I installed
it. I figured it would never be a problem. Alas, I erred.

I don't know. But the heat was definately a contributing factor because the
damage was at the bottom bend, the sharpest at 90 deg, and on the inside of
the wrap where it's the hottest.
