Dynamat - worth it or not?

[Troy711]

I did my brothers ssv wagon with it and it made a bit of difference, wouldn't say it completely blocked all of it but there was an improvement for sure, i used dynamat xtreme. If you want some i have some left over, 4 or 5 sheets from memory if you're interested.:whistling

How much did you end up using? If it was a pack and a half I might be interested in the leftovers you have.

I'd have to have a look but i think it was 4 or 5 sheets which means i have 4 odd sheets left.

Hmmm you all sound pretty convincing I'm interested in doing it now

I was going to do the whole boot and wheel arches but unless you know how to take the trimmings off and have plenty of time on your hands say three quarters of a day then no point. Also the boot of the wagon has a plastic shell that is ribbed. So putting dynamat over this might not work. That's what I was told by a panel beater. I wasn't game enough to rip everything apart!

I laid the dynamat over the plastic ribbed boot of our wagon and it has held fast. Had to as it doesnt stick to carpet so its hard to line the underside of the spare wheel cover. I was more worried about the vertical walls of the doors but it stuck fast in their. Its good stuff.

I used 14 sheets out of 18 sheets. It was the Xtreme stuff.

I had the entire cabin of my SSV ute dynamatted with dynamatt extreme and whatever the dynamatt is for the floor (it's different) - made a huge difference to noise as I have 3 inch exhaust etc - won't block all the noise out as noise comes through the glass and but also makes fantastic increase in sound quality of stereo although i have added an amp so stereo better anyway -won't get rid off road noise though but it does dull it

Cost about $1500 installed

I am absolutely not an expert in this, but if you search the specialist car audio type forums there seems to be agreement that there is no point doing the whole of each panel.. I forget the recommended % but it's something like 40% I think. Not trying to be controversial. Just passing on what I have read elsewhere.

 

[StoneX]

That percentage is to stop the panel resonating. In this case they're using the Dynamat to block the sound so the more, the better. Personally, I'd Dynamat the whole panels and then put a layer of MLV (mass loaded vinyl) or closed cell foam.

In my old VT I actually, deadened with a Dynamat alternative and then put carpet underlay under the whole floor pan and it worked really well. But I don't think underlay is closed cell so I wouldn't recommend it for in a car.

bit off but trying to get some suggestions if any of you lads did the dynamat on the front door with bottle holder in the door trim (like VE SV6).
So if you covering the service hole in the door with dynamat stuck flat, was there any trouble putting the trim back if there was no dint shape in the dynamat like in the stock plastic sheet.
Any help will be appriciated..

You're gonna have to 'loosely' cover that service hole otherwise there's no way the door trim will get back on properly. Stick the top part of the sound deadener on first then push the center in a bit then stick the rest of the sound deadener around the edge of the service hole.
