Dynamat - worth it or not?

I've been thinking about dynamat for my car too.... doing the doors at same time as audio upgrade, and also the boot as you've described. But I'm too much of a softy to rip apart my car (and I'm a complete noob when it comes to audio and soundproofing).
From what I understand there are different types of dynamat available- thin shiny one and thicker black one, and in different sized packs. As Troy has already asked above, what sized pack is best and at what price?
I'd even consider a 'group buy' for Canberra folk interested and maybe we can all get it for a better price.... just spitballing at present, I have no idea if such a deal would net any real savings?

According to dynamat website, there is a specific product kit for the boot available (which by the looks of it has the normal thin shiny stuff as well as a liner of some sort over the top). Here's a link to website: Introduction

Or there's this stuff specifically for the floor to stop exhaust noise: DynaPad

 

I havnt had any experience with the ve but from what I have heard/read, people get great results from this stuff. Apart from the apparent weight gain, but unless your morton its worth it.

Deffiantly worthwhile, just did a mates boot full of the stuff, works good if you know where you're putting it :rofl2:
Buy a bulk pack if you plan to do the wheel well, if you got spare you'll always find more noise lol. The tape is also nice if you want it to look clean etc. also SHARP knife is a must

cheers - JD

ps. dont buy cheap imitation stuff it doesnt work half as good!

 

Not sure how effective it would be on the boot of the VE due to it being plastic?

 

Personally, I would put a closed cell foam or something over the Dynamat to actually block/absorb the sound. The bulk pack is the best value for money. You can get it on eBay but beware of sellers who have removed a sheet (it should have 9 sheets). FHRX in Sydney also has good prices on it and posts it

The last price I got was in January and it was $230 for a Dynamat Xtreme bulk pack shipped.

 

Definitely made a difference. We lined the doors and the cargo area including under the spare wheel of our wagon. The stuff is easy to cut, easy to apply and it stays put. All you need is someone who knows how to remove the door trims without braking the clips, scoring the paint or putting a screw driver through the trim. The guy who tinted our windows had to remove the door trims so we lined the doors with dynamat while the trims were off. Our auto electrician (the guy who installed the DVD players, iPad dock station and remote start button) said we should use the rest of the dynamat to line the wheel arches and reduce road noise. Sounds like a great idea to us but we'll wait until the shocks are replaced and the wheel arch liners can be removed more easily. The stuff aint cheap but it definitely made a difference to us.

 

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

 

did the whole firewall/floor of the pala' minus the boot. makes a HUGE difference. not only that, its a nice protective barrier against water [read rust]

highly recommend.

 

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.

 

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.
