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;
