Ive thrown in 8 sheets to the front of the wagon (over the top of the dynamat) on the floor pan and a wee bit up the firewall and it has cut out more of the road noise. only cost 90 bucks and 20$ for a can of spray on adhesive.

what about this product from Jaycar , seems to combine Buty and Foam

I did look at that but it's only 3mm thick..Quote:

If your looking for a solid decrease then the only way to do it is mass loading the panels the a good thick layer of sound absorbing material.
so compared to that, Luxary Liner Pro looks better
Specification
Sheet size = 24" x 54" (9 sq. feet)
Thickness = between 1/4" - 1/2" (.25" .5")
Mass/Area = 1.2 lbs. per sq foot
Total weight per sheet = 10.80 lbs. per sheet

That does look better on paper..
has someone done yet a dampenig job for a Y60 gr
Yep, we've only done y60'sQuote:

I think that's mission impossible mate. I doubled up the fire wall and still get engine noise. Greatly reduced but it's still there. I'm Na, so turbo should be better
I have been through same process with dynamat throughout and main issue is also now engine noise (td4.2 + t) - I am looking at bonet lining to help reduce engine noise and wondering if anyone else has done this and if so what brands and success ?
The foil lined stuff I used is supposed to be good for bonnet..
Thanks Biggqwesty will look into it. Dynamite also has a bonet liner I think
Cbeers
Hey biggqwesty was there much difference between the insulation ebay stuff you bought compared to the car builders stuff, what was the deciding factor going ebay?Quote:

Nope. Well not that I could tell.
I received a sample of both, but had the same cell structure, feel and weight.
So apart from the foil top I think the main part, the foam, is identical.
Just one is plastered with brand name and the other is not
Dynamat helps and there are the spray on kind, I think they called lizard or something like that cant remeber.
There are heaps of different paint on / spray on types. But all do the minimum.Quote:

This stops vibrations which is the cause for some of the noise, but to stop external noises like tyres engine etc you need that extra thick absorbing barrier, that's were the foam comes into it..
Have a read threw the link in the first page and it's explained in more detail
I'll also add that the bitumen based products do work but fail in the heat.
The dynamat is butyl based and will hold in for a lot longer
Just did the front doors both inner and outer skins with the fat max product,
Huge difference to the sound quality, now it sounds like a doof doof mobile.
It does hey.
Did you do just the rubber part or foam aswell?
My experience was that the Car Builders foam was a better quality and denser than the other stuff I got from Clarke Rubber. The adhesive also seemed stronger. I ended up using the Car Builders foam for the floor areas, transmission tunnel etc. and the cheaper stuff on the ceiling. Time will tell I suppose.
Re the Butyl compounds like dynamat and what Westy got from the Bloke Depot on eBay, I honestly couldn't tell the difference. I ran out of Dynamat and Westy sent me some of his leftovers so I have it pretty much side-by-side.
I did dynamat the underside of the bonnet too. Not a complete coverage, but probably 75% as I had left-overs. I reckon it made a difference as well.
I just used the rubber part, so only a slight improvement in noise reduction,
But I didn't think the GU was to bad anyway.
Interesting reads here. I know this is an old thread, but I'm about to start this process with my 99 GU. Except, the goal is thermal insulation instead of just sound dampening. I know there is some overlap between the 2 goals, but thermal insulation is of the utmost importance here in Siberia when dealing with the winter conditions. Will have to post up some progress pix as I get into it.
So how did your job finish mate??Quote:

Hey Westy, I can't get Dynamat over here but there is a company that can do a spray on rubber liner - same as what you would use in the back of a ute - do you think this would work for some sound deadening if used under the carpets?
It may.. any material stuck to the body is "mass loading" the pannels, it's just how much mass is added.
I noticed a small difference when I painted my rear 1/4 pannels with the paint on stuff..
It didn't do as good a job as the dynamat but it did something..
Its an oldie but a goodie is to stuff some
acoustic batts inside the rear 1/4 panels.
You'll be surprised the difference it makes.
Westy, sorry I didn't see this until now. Yes the job is finished. I used a product over here called Shumoff - a dense 10mm self-adhesive insulation. Insulated the roof, pillars and sidewalls of the cabin. I didn't do the floor because the GU already had a thick pad and carpet. If it still gets cold, I'll go ahead and do the floor as well. I noticed a definite sound dampening and it so far has held the heat very well in -40C temps. So far I'm very pleased with the results.Quote:

cheers
painter recommended to me use body Schultz. under the car haven't done it yet so cant say how good it is
Yeah i was more talking about coating the inside of the cab/floor pan, im interested in a primer/sealer before i lay the matting.
