## Questions & Answers

**Q: Can you supply a piece measuring 35” x 56”**
A: Unfortunately these are only available in 1 size, pre-packaged from the factory.

**Q: Is this suitable for use with silent coat multilayer inside the doors for extra sound dampening? worried it may be too thick.**
A: It might be ok, but as you say thickness could be a problem. Would depend on the car. I used this to cut down the noise in my camper van on the floor in storage spaces. Your best bet is to get something like Dynamat. It's thin, really damps drumming , rattles and road noise. It's not cheap but it sticks in place and works!

**Q: Looking to use this between my engine cover and the engine, is this suitable as it will be touching hot parts of the engine?**
A: This product is fire resistant and perfectly suited for use in an engine bay however it is not recommended that its operating temperature exceeds 100 degrees C.  Direct contact with engine parts is not advised.

**Q: is is suitable and safe to use under bonnet to stop engine noise?**
A: That is exactly the products purpose. It is self adhesive (make sure panel is grease and oil free) and the 20mm acoustic foam is designed to absorb engine noise. The product is fire retardant and high temperature resistant with a foil heat shield. Just ensure it is kept clear of exhaust manifolds or turbo units where temperatures exceed 100°C

## Customer Reviews

### ⭐⭐⭐⭐⭐ Noticeably quieter
*by D***D on 2 August 2016*

Used this on the bonnet of my classic Mini Cooper. There is definitely a reduction in bonnet vibration and heat. Engine noise transmitted through the bonnet is also noticeable reduced. Worth noting that this reduced bonnet heat obviously means your engine cooling will be reduced - worth considering if like me you are putting this on an older car.About 1/4 of the material was left over as my bonnet is so small! Trying to think of somewhere else to use it...

### ⭐⭐⭐ Three Stars
*by R***E on 14 May 2016*

deadens noise slightly

### ⭐⭐ Two Stars
*by A***R on 6 December 2017*

Placed under bonnet/hood.. No real difference.
