Did you use that special roller to apply the sheets ,BTW bloody big job there buddy. lol
No.. But Geeze my hands are thanking me for it.. LolQuote:

I'd recommend the roller.. :D
Wife reckons I'm building a space ship!! WTF..
Sure she'll be happy with the results,,
did you slide some pink batts in the 1/4 panel cavity?
No but have covers right around to the doors, in and around the fuse box.Quote:

WwwWell I picked up this stuff

And shoit Its thick..
$45 ish from auto barn.
As I suspected its basically paint on rubber / tar, but I don't mind as iT's going in the rear 1/4's, wheel arches and the few spots I had to weld repair to give those areas the original coating..
Well, shoit it's thick.. Buy throw away brushes.. And some rubber gloves..
You get a lot of coverage from 4L.. I'd say easy a few coats of the whole floor pan (but keep reading), after applying a good coat in the 1/4 (slapping it in) I used roughly 150ml..
This stuff is good for sealing a surface, but in my opinion has nothing On the dynamat..
After 1 good coat there is no difference between coated and uncoated panels, where with 25% coverage of the panel with dynamat it had a huge affect.
So imo and as I suspected its no good for "sound dampening" as it has no weight to it (refer to link in first post), but
Sealing, rust prevention and mess making.. Yes it ticks those boxes.
But in another side note, 4.5m2 of dynamat has covered the car. I didn't do the cargo area Floor as the draws add a huge dampening affect, But I have enough left over to cover the inner skins of the front doors. So if you want to do the cargo area it's perfect.
I went with more a 75-80% coverage with the dynamat. If you stretch it to 25% then the 3.5m2 pack will do..
Are you painting the inside of wheel arches with this "stuff"?
Yep.. But shoit it's sticky..
Might have to do this next year, after You give your opinion of it, is it worth doing or not.
I can't wait to try it.. Got a few more bits to put in.. Will be scraping Christmas. Plan is to take it.. Fingers crossed..
Well Its driving. Still some loose ends to tie up with body work but Its driving..
And wholly hell what a difference.
It's on par if not quieter than the in-laws diesel prado, and a lot quieter than our petrol BA wagon..
Worth while. Hell yes..
If it's something you wanna do, do it..
what was the total cost of it all.
Time!!!! Lol
Um seriously cost me $350 for the foam and butyl mat..
We'll guys got it up to highway speeds tonight. Loving it.. Wife and I can talk nicely. Lol
You can still hear the diesel engine, but it's more a dull rumble, not like your straddling it.. :D
No road noise at all.. I'll admit I'm only running Cooper ATR's which are a nice tyre but it's a huge drop from before.
This is with no draw system in so once thats all fitted again I guess it'll be better again..
You still get the wind noise coz let's face it, we ain't drive the most aerodynamic cars here. I think parksy is keen to do his roof so I'll let him test how that goes..
I was thinking maybe another couple square meters and do the bonnet, but we'll see..
So again.. Very happy with the outcome. And for it still to be wash out if needed is a bonus..
And that right there is exactly why I won't be doing any sound deadening to mine, I prefer to listen to the constant drone of tyres and car rather than that sort of drone!!!!!!!Quote:

Well I have noticed another little bonus now I'm driving it more.
Outside temp is low 30`s but the air coming in threw the vent is still cool.
So I'm guessing the extra insulation is keeping the whole system cooler..
Westy,
I hope you don't mind, but I am half way through some of my own additions of sound dampener, and thought that perhaps I could just add the pics to your thread.
Starting with the floor in the front of the GU...

I actually did right through and under the seats but that is as far as I have gotten so far.
Drivers door.... basically covered probably 80% of the outside door skin wherever I could, and then most of the inner door. I would like to cover as much of the hole where the door lock rods go through but am out of dynamat at this point in time. Have also done the outer skin of the passengers side door but that is it.

Hopefully I can finish the doors and the floor in the middle seat area sometime soon.
Put the door trims back on and took it for a drive this arvo. Fantastic improvement in sound from the drivers door, and in general from the install so far. I didn't go ballistic on the firewall as I decided not to take the dash out yet like you blokes did. All the same, very happy with it, so thanks for the tips to start with from yourself and Parksy that gave me the motivation in the first place.
Not at all mate. It's why I put it up separately, so people can find it and use the info..
I would also add the foam to the outter door skins, maybe a pita with the stuff on the inner skin. Did you have a look at the link at how 24% coverage with dynamat is optimum? Will save you a bit of cash..
Thanks, yes I saw that. After speaking with 04Off though, I decided not to put any foam in the doors, and to up the coverage on the dynamat with the aim of a bit better sound as well. I won't be doing that for any of the area behind the front seats though.
I have lined all the floor from about just behind the front seats forward to the firewall with new foam as well. Unfortunately I must have forgotten to take a pic of that. When I finish off the vehicle to the back, I'll take a few more pics.
Just quietly I am very pleased with the difference now in the sound from my 6" speakers, even though they are relatively crappy ones. Makes me wonder what a good set would be capable of. Maybe another project down the track...
Yes I'm still running stock gq fronts and 6x9' in the rear doors and they sound good. Might go some splits I'm the frontQuote:

I wouldn't waste it mate.
As linked earlier in the thread the optimum coverage is 24% from memory. Any more and the gain is minimal.
I'd even it out and cover as much as possible.
The dynamat is not the stuff which reduces noise either, all it does is mass loads the panels to stop vibrations..
You need a thicker, dense cover for actual sound reductions.
Really?
This is what I was thinking of doing from a prev post....

Here is a snapshot of what I'm doing
Ok you have 2 different things going there.
When you put the dynamat on the outter skin, ie floor pan doing 100% is a waste as mentioned before..
When applying the inner skins of doors as in your last pics your not really sound deadening but more increasing the audio sound..
Best audio comes from a solid wooden box. We can make doors from wood so applying 100% dynamat give the weight needed for the steel to act like wood..
You will still see a small decrease in exterior noise, but not as much as if applied to the outter skins
Have a read of the link in my first post, it explains it better.
Everyone's hearing is affected by different environmental factors, low frequency, high freq, background, etc, so there will be different outcomes. I put a foil/butyl layer down on the floor and outside skins as well as inside door skins. What I did then was put a dense but thin, like 6mm, down over the top of that on the firewall and floor then put, with difficulty, the carpet/moldings back down. With my hearing the reduction in background noise with the ability to hear conversations front pas and rear pas seats was incredible, is as good at the European thingy.
When insulating engine rooms on a few boats there is a material that combines a lot of what has been talked about here, three-four distinct layers. Foam/Lead or HD material in lieu, and foil, it's anywhere from 1" (25mm) to 2" and very heavy. My reading are that sound can escape even through the smallest imperfection or gap and that is why we taped all the seams too. http://www.fisheriessupply.com/sites...ec&id=Soundtec
Now it's pretty impractical to put a 25-50mm layer down on the floor but one could put some of this stuff in doors and cavities. I wouldn't know where to source this.
Spot on. I layed a 25% coverage of dynamat then 100% coverage of a 10mm mass loaded closed cell foam with aluminium foil topping, then struggled to get floor in..
It went in but tightly lol..
And same, can now comfortably hold a conversation with the wife.
Sometimes I wish I'd left it alone...
;-)
Well the dynamat went in and its definitely quiter.. But now I'm thinking how to get it quieter again haha.. So next step would be closed cell foam?
yeah closed cell foam will do the job, something like this http://store.secondskinaudio.com/lux...q-ft-4-sheets/ this one is a mass laoded vinyl barrier with closed cell foam.
Shipping would be murder to nz I suspect. Hard to find that sort of thing here - bugger.
Have a look threw the thread I've linked the product I used.
10m2 and I had a peice 450x450 spare.
It covered all outter door skins, fire wall and floor.
Mine is a LWB so don't buy that much if you have a ute..
$200 I think it was delivered
Here it is..
http://www.ebay.com.au/itm?itemId=251263917315
This stuff is exactly the same as what is used in high end cars and fit outs..
Just tried that link but no workey. I am also in nz so might keep us sheep shaggers out
Edit: I found it searching that product code, Looks like they dont sell it anymore?
Edit 2: http://www.ebay.com.au/itm/301224841696#ht_13784wt_900 looks similar?
That's the stuff.. But a pit pricey..
I paid $20 a square meter.
But your onto the right stuff
thanks mate, I ended up getting this instead.
http://jaycar.co.nz/productView.asp?...g&form=KEYWORD
stuff some acoustic batts down your 1/4 panels , you'll be surprised with the difference
Was also going to get that stuff untill it was found not to have a self adhesive layer..Quote:
