Dynamat extreme in Montreal

Sorry guys, I know it may not be the best place to post this but I am a bit in a hurry because willl spend a few days in the Montreal, Canada area next week and I want to purchase some Dynamat Exterme stuff (I was considering buying the bulk pack) in a store in this area.
Can anybody suggest a store?
I want to buy it tomorrow if possible through the Internet and have it shipped to my hotel since I will not have time available to go and buy it myself.

I want it to do reduce the noise and heat a bit in my defender

thanks !
SG

I wouldn't bother with all the effort and the haul back. The stuff really doesn't work all that well anyway. The only proven way to quiet a Defender is turn it off.

I just bought some Dynamat Extreme from Crutchfield as part of my radio/speaker order. Santiago - the website is www.crutchfield.com if you didn't already know. Crutchfield is a pretty big mail order company so I am guessing they might be able to help.

The stuff isn't cheap but I'm just installing in the doors to hopefully help with the new speakers. I'm not expecting much but would love it if the Dynamat helps with the tinny sound of the doors.

Check to see if Best Buy or The Source aka Circuit City carries it.

I wonder how it compares to "brownbread". I used it in a '65 mustang a few years ago.
I see it has been changed....but at the time it was supposedly superior to dynamat.

you may want to compare the specs

Do you guys agree with Buck?

Doesn´t it make any difference aplying some Dynamat to the floor?

Thanks for the data!

I agree with Buck. I think I added 70-90 pounds of the stuff. The only place it is noticable is under the hood. And not for noise. It cuts down on heat to the hood surface, making it touchable. Otherwise, I personally feel it was a waste and will be a pain to strip out some day.

The only place I did not yet put it is on the bulkhead. I was waiting for the day I swapped to a new bulkhead for this effort. Not sure if I would still do it.

David,

Have you used exactly the same stuff: Dynamat Extreme?

Cheers,

6 of 1, half dozen of the other...

Some people swear by it. http://forums.hybridz.org/showthread.php?t=98865

This is a really detailed article that discuss a lot of different product choices like Dynamat Extreme, B-quiet and a few others... http://www.sounddeadenershowdown.com/

Yes,

Back when I cared about noise I put it all over. Spent $200 on the stuff, didn't notice a difference at all. Then had to remove it and cursed the whole time. The only thing that made a noticable difference for me was carpet. But it started to stink.

Yes, the extreme as well as hoodliner in the roof and hood.

I never liked lining the hood as it merely reflects heat back at the engine. At least the hood transfers it out.

But, in all honesty, I think this is being made a bigger deal that it deserves. If you move the intake to the front of the bay to get cooler air that's all you need.

Here's what I like:

1. Do not put anything sticky down that cannot be easily removed. Do not use those spray-on insulation products!

2. Use acoustic foam lined with aluminum for heat reduction in the foot wells and the roof. A white painted roof cuts down on heat but a little more reflection deosn't hurt.

3. Acoustic foam in the doors, rear floor and rear wheel wells and inside seat boxes for noise control.

4. Double up on these if space permits. Lay down thick carpeting where necessary - use outdoor, synthetic types that don't get musty/moldy.

The key is to cut these panels to cover as much area as possible. Make them removable on vertical surfaces with a tack of silicone or velcro for all you anal types. Plus, they're lighter than Dynamat-type stuff that's doubled-up or more for equal effect.

Of course, for a trail truck I don't see why you would bother with all this crap.

If you have a station wagon then you will probably notice a difference. I went a different route and used a product that is used on roofs in winter climates, it's called Peel N Seel or something like that. It is similar to Dynamat. I bought a 100 sq ft roll for $89 and did my entire truck cab including the ceiling and under the hood and I still have a bunch left over. My truck is very noisy and it made a huge improvement in noise and reducing heat transfer through the firewall/bulkhead. I can actually listen to the radio on the hwy now. Do as much as you can. I did the doors, seat boxes, floor, footwells, transmission tunnel etc... If you have a soft top it will still help deaden sound but IMO it would not be worth it, although at $89 to do your entire truck it's a cheap investment.

Marchand's is a SW.

Always thought the roofing stuff was essentially the same as Dynamat but by your experience that may not be true.

Only thing I would do differently is not stick it directly to the truck where rust may develop. I'd like to check periodically for rust and covering it up with stuff like this doesn't sit well.
