sealant
hi everyone.
i need to build a generator shed and in a process i have to cut a hole through iron sheets for generator exhaust pipe. i dont know which is good material to use to seal between the exhaust and the iron sheet to avoid leakage. a material which is heat resistant and flexible enough to resist all generator vibrations.

if the temperature is low enough at the penetration, i would be awfully tempted to use a dektite flexible seal;
thanks jadeclampett
