I looked up damping materials on various threads.

This stuff from Owens Corning (Fiberglass Pink people) looks good: http://www.owenscorning.com/around/r...derlayment.asp

I also found it here with pricing info in a wholesale catalog: http://www.reesewholesale.com/catalog/103.pdf

Unfortunately it's not available in Canada because Owen-Corning doesn't market their roofing materials in Canada.

Just out of curiosity I called Home Depot in Bellingham, WA, USA and they carry 66ft rolls of the stuff for $68usd each. I think the lady said they have 23 rolls in-stock.

It also comes in a 33ft roll but they prob just carry the 66ft roll. It's 50mil thick or around 1.5mm with a self-adhesive backing and the roll is 3 ft wide.

It was suggested to cut it into smaller pieces which is easier to apply and will stick to vertical surfaces as well.

I really want to try this stuff as Dynomat and the other audio name brands are such a rip-off.

Looks like I'm going to have to make a run south of the border to get it though. I can't even special-order it here in Canada. Sucks.

Oh well.

I just bought a couple new amplifiers so I don't want to tear my interior apart to mount them without doing the dampening material, might as well do it all in one shot. At least a 66ft roll is enough to do my truck, the wife's car and probably another car.

Kind of odd... this stuff should be sold in Canada to protect our roofs from ice/water damage over winter.

 

I bought a roll of the stuff today. You can see pictures of the box it comes in and the material itself here:

I applied some of the stuff to the trunk lid of my brother's car. I have to say it doesn't stick all that great but I didn't clean the paint with alcohol or anything. It may help to do that. I'm probably going to stick to floor surfaces in my truck and look for something else for vertical portions.

It seems to stick like hell to it's plastic pull-off backing when warm in the sun, perhaps it needs a heat gun to work better.



I'm still experimenting.

 

I broke down and bought a Dynamat "trunk kit" yesterday. It was on sale. LOL.

So I'll be sticking that to the rear cab wall and using the other stuff for the floor.

 

Well... Dynamat "original" is pretty much crap. I'd leave it for stuff like floors because it doesn't shape to anything without the glue coming off. Dynamat "premium" is pretty good, stick well and shapes better, slightly thicker than the "original" stuff. Worth buying. Dynamat "Extreme" is really nice stuff. An aluminum layer with this black goop on it which sticks to everything (keep it off your cloth seats!) and shapes over and around anything. Great stuff. Too bad its so damn expensive.

Make sure you use rubbing alcohol or something similar that doesn't leave any residue to clean the panels before sticking anything on it.

Once you have the seats and the interior out you'll be surprised to see how *thin* the metal is in the floor, especially under the seats where no weight load is. In the back where the passenger's feet are and the front foot wells they're reinforced with this 1/16 layer of epoxy type insulation material (hard to the touch) that makes the *thin* sheetmetal in the floor seem very strong.

Adding material to the side wall behind the driver (opposite the 3rd door) is difficult. There's only a small hole barely big enough for your hand to lay dampening material on the outside sheetmetal, but very easy for the inside sheet metal. Laying material in the 3rd door is relatively easy.
