dynamat aerosol can

Don't buy the spay on stuff. I have never gotten a can that wasn't at least half way dried up.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

agreed auex... I stay away from Dynamat period...I prefer the Brown Bread peronally, but have only ever used one spray that was even somewhat decent, and I think it was by Cascade Audio...but even then it wasnt as good as using the brown bread itself...

I've just recently used the spray on stuff made by 3M and it has fulfilled my needs wonderfully

Old thread revisited, again: This is a Quote from Me taken from back in November: Kinda depends upon the application location. If it were me, I would get a little of both.(talking about brands of sound deadeners) Use the stickeiest stuff on vertical locations and the less sticky on horizontal locations. I would suggest buying about two to three cans of spray foam to pump into all the cracks and creveses between the body panels and frame work and to fill in big holes in areas. It may sound a little messy but the end results will be spectacular. (just make sure you pay attention to where you cars venting runs so you don't fill them.) With a little work I made a foreign tiney pick up sound like a caddy! You couldn't hear my designed system that put out 150+db with the doors closed if you were next to the truck. (owner/installer)

I have tried a couple different brands of the spray deadener. They all seem to work the same to me. I have found out that it takes 2 coats of the spray to equal one layer of sheet deadener. I used the spray in places that I couldn't get the sheet kind. Pioneer DEH-P980BT, Zapco DCREF1000.4,Pioneer TS-C520PRS, Adire Extremis, MTX TA91002, TC Sounds TC-3000 15"

I also used a product from Autozone that basically a undercoating that protected from rust and road debris. It also stated the it was to be used for sound deadening. I tried some out on some spare wood and it set up really good. It does have one draw back, it takes awhile for the fumes to go away. I wouldn't advise using it on the interior of the car if you don't have plenty on time to let the areas air out. I used 12 cans for 4 coats on the complete underside of my car. It's only $3 which is alot cheaper that the Cascade or Dynashield cans. It drys a flat black which works great for the underside of the car.
