I have used this several times when installing diesel heaters in various camper van builds. I use it to seal the underside of the van to make sure NO carbon monoxide is able to get into the van from the exhaust opening, even when firmly screwed into the floor. This product is able to withstand the extreme exhaust heat of a diesel heater. Be forewarned that it is messy and gloves and lots of clean-up material is needed, even when you are very careful. Do not let it touch your hands (per instructions), nor breathe it in while applying. This is used to seal exhaust hole, not as an adhesive possessing much adhesive strength.
