## Questions & Answers

**Q: I have a Gas Club Car Carryall (Golf Cart)....My question: Would this Thermo-Tec be of much use to dampen/deaden the engine sound from my golf cart?  I am considering placing some under the bed of the rear of the golf cart, under the front seats, and even possibly the floor board of the golf cart.  Would this work good…**
A: The material does add weight, buts its sound dampening appears quite good. A golf cart has less weight issues, it seems to me, than an automobile. It appears that you have a motorized golf cart with a 4 stroke engine (I am familair with the quiet electric carts) so I don't know if your results will be worthwhile.

**Q: can you use this on your exhaust muffler??**
A: no, it may catch fire. Maybe you could add it on the inside above the muffler area. It would definitely help reduce the outside noise inside the vehicle.

**Q: Hi, Is this the original silver version or the new black?**
A: Black

**Q: Will this work on a tailgate door on a jeep wrangler?**
A: Yes if you are getting resonance from the tailgate.
