Sound dampening..

[BigRAWesty]

We my local shop said yep it was. He could be up for a few cans of gel grip..

Also am being sent a sample of the car builders 4x4 Mat. A little more expensive at $60 PP for 1.8m2
Is 5mm thick and looks dense.

The epdm source has it all pre packed so cant supply an Off cut.
But is a bit cheaper at $29 for 1.1m2..
Is also 5mm think but looks more pliable from pics..

Would seem the first guy's use there product which is a good sign..

ok, have made my decisions..
Going >> This << as the base.. I will cover complete fire wall, driveshaft hump and the rear wheel arches, plus either a whole sheet or half sheet per door skin depending on whats left..

Then >> This << for the top layer.. Have done a bit of research and after RLI jumped in stating his stuff workes i have a confidence that this is the same as the water proof stuff that i posted before.
Closed cell rubber foam with a aloy film on top..
10m2 for $200, no one else comes close..

anyway, i think this is a good medium setup, water proof and will assist that ac when in the outback.. lol
so ill keep you guys posted.. now for the complete tear down...

Looking on with interest you haven't got me yet. thinking I like what MudRunner has done,
by brushing it on as it can't trap moisture, suppose each have good/bad points.,
did you do the batt down in 1/4 panel cavity, hell of a lot of noise from that area.
I watch and listen lol

That stuff that RLI got from Clark rubber is also perfect to make window cutouts with for the rear cargo windows get the wife to sew a nice trim around the border and pop a couple of holes in it to place some suction cups from spotlight and Bobs ya Auntie

Kallen in terms of water proof. I liked the brush on as it can't trap water. I did 4 or 5 thick coats and if I am ever dumb enough to flood the car again then out comes the carpet and the water will be manageable. If you can get water between you floor pan and the sheets I think your asking for trouble. My 2c

Fair points, was there any smell with the paint on stuff??

Zero. Nada! Not at all.

That link you posted was interesting too as it talked about allot of he noise was reverb through the panel steal like a drum. So the 25% rule applies (can't remember the percentage ) even just painting a couple of coats on the inside of the door skins would stop the reverb from happening I think. It would be less inclined to vibrate.

It's cheap and easy as. Putting something on the fire wall would be a real winner though.

That first product is the same concept as the paint.
2mm think rubber sheets, at the 25% rule (except the fire wall and wheel arches), Then the water proof foam will cover 100% of the doors, 1/4 panels and floor..

By using the paint you get 100% water proof I guess.
What sorta $$$ per liter and where do you get it??

One thing I've noticed with the dynamat(butyl) is that it sticks extremely well! Especially compared to the fatmat(which isn't true sound deadener). I've applied it using a roller and I very much doubt that water will find it's way under the sheets. So long as there isn't any points that the water can enter from under the sheet, I don't see any problems. I think it would actually benefit the steel underneath. I only draw this conclusion from removing the tape used to secure the wiring looms to the floor and revealing mint condition floor underneath.

Hey Mudrunner, what is the name of the paint on stuff you used? $$$$? Where did you get it?

As it stands, my patrol has most of the floor section, drivers and rear barn doors and firewall covered in sound proofing material, and the difference is amazing! Driving to work and back today and the traffic jams didn't even bother me because I was in awe at how the patrol felt and sounded. I covered the transmission tunnel in dynamat, and I can't hear the clunking gear changes, which almost makes it feel nicer to change. I did start off with fatmat, but I'll be ripping this out and replacing it with dynamat. Then covering it all in acoustic liner made by car builders. Will also do under the bonnet and chuck on some hood liner aswel. Great way to transform a car!
