[Public-List] Exhaust iron/steel pipe thread sealant

[gdinwiddie at alberg30.org]

I don't recommend teflon for exhaust systems.

"DuPont studies show that the Teflon off-gases toxic particulates at 
446°F. At 680°F Teflon pans release at least six toxic gases."

This is well within the range of internal combustion exhaust gasses. 
While the cooling water might keep the pipes below that, I wouldn't bet 
my life on that always being true.
