Anyone have an alternative to dynamat?

I once heard that there was some kind of material at home depot that was the same stuff as dynamat. Has anyone ever heard of this? Or... is there some other alternative?

its called peel and seal and it works ok. Ive used it here with no problems, but it doesnt get that hot here. there is some people that say it doesnt stay stuck, but they are usually in hotter climates

check out http://www.secondskinaudio.com for some good deadener at a reasonable price

Ok, thanks. If the "peel and seal" is drastically cheaper, i may go with that. I live in montana so it doesnt get too hot.

not that much difference, If i was going to deaden something i would use the foil backed stuff from second skin. its butyl based and lacks the nasty asphalt smell that peel and seal has

ok, thanks

peal n seal will stick and stay stuck no matter the temperature if u heat it up and roll it with a sprocket roller. it would never come off

the problem is when it reaches a certain temp it liqufies and the foil backing begins to slide. Its the same as when you park a motorcycle on hot asphault and it leaves an indention

That is like saying that you can glue ice to a wall, as long as you heat it up first...

The only difference is that Ice melts/liquefies at 32 degrees f. and asphalt does the same at 180 degrees f.

Asphalt is non-curing. Just like water.

It can go from a liquid state to solid to a liquid state countless times until all the volatiles evaporate or work out through osmosis.

Then, once the volatiles are gone, so is the adhesion and the elasticity of the product. And you are left with a brittle mess. Just like mixing some corn meal in to some ice. Freeze, thaw, freeze thaw.. Heat the water up enough and it becomes a gas. AS the steam escapes, eventually you are left with nothing more than the cornmeal filler, and in the case of the asphalt, you are left with nothing more than the filler and additives the roofing companies add to the asphalt to cheapen it up.

Heating the asphalt up does nothing but slightly melt it. That’s why it gets stickier when hot.

But once the material heats up again, wheat do you think happens?

Yup, it melts again.

Heating it up the first time, is not some magical sort of secret method that locks the flash point and viscosity in place forever.

Regardless, asphalt will always, always melt at 180 degrees F.

Indeed... P&S will fall off eventually, even if it stays on a few years. I installed it very carefully in one of my previous cars... clean surface, heat gun, smaller strips w/ aluminum tape around the edges of each and every piece, etc. It stuck for ~4 years and is now starting to come off and ooze out, even around the tape -- my cousin owns the car now so I check on it from time to time.
