Morning all, does anyone have details of what can be used as sound deadening material ?

I'm looking for something that can be stuck under the bonnet, and against the firewall to minimize the noise.

I found this online:
http://www.autostyle.co.za/sound-deadening-mat.html

as well as this:
http://www.plasticworld.co.za/products/Thermafoam Ductwrap.aspx

Any other products available?

I heard of a couple of people rubberizing the interion of their G's, does this make a big enough difference?
I have used the Ductwrap/Thermafoam product (or very similar), mentioned by Plasticworld with success as bonnet liner and firewall insulator in a Jeep Wagoneer which I restored about 12 years ago. More recently, I have also used it in a small John Deere garden tractor. I suspect that it has more heat insolating than sound deadning properties.

These products all have some noise reduction effect, some just better than others. E.g. I don't think rubberising will give a dramatic reduction. You will never "retrofit" to get a whisper quiet vehicle.

I suggest that you Google the subject for more products. Also search pointedthree.com as I recall discussion of this subject.

I used a Sondor Tapes (Sebenza) Fireproofing sheet under bonnet. I think it helps for noise but the biggest difference was heat on the bonnet and this makes the air coming in the cab cooler.

A lot of noise comes into the cab via the transmission tunnel. There is meant to be a heat/noise shield in the tunnel underneath and then the original foam vynil mat inside and finally a console and the rubber boots around the gearlevers.

I have also found hard engine mountings to cause noise.

That first link of yours looks good for the floor. There is also a waterproof roof flashing which is a heavy alu foil with bitumen which I may use on the floor one day also. For sound and rustproofing the floor.

Agree - Those rubbers on the gear leaver and transfer case makes a difference for sure!

Hi
Attached is an invoice of a product I used for my 230GE and my LR110; good results.
Also had new carpets made for the G and this also reduced noice.

Clive, would you mind show us photos of the G carpets. The carpets that come with the Professional is a shame.....

No knowledge on the product but can imagine it quickly adds up tillyou are finished.
I did hear however from people that have used the standard aluminium backed bitumen one uses for fixing roofs to work well.

Has anyone seen / used these maybe? Looks like a desend product?

Thoughts from the technical clever guys?

Also have sound dampning products

https://www.secondskin.co.za/
No personal experience, but I've read of several US based mog owners who used second skin (or dynamat - a competitor to second skin) with success. I was planning to go this route on my mog, but sold the vehicle before I got around to it...
These products are expensive, but from the reading I've done I was convinced that it will be worth the cost.
