Spray on sound deadening

[KB777 10+ year member]

I have seen a product that is a sprayon sound deadening and heat reducer. Will this work as good as something like dynomat? I know it would be a whole lot lighter. What is the best thing to use?

That aerosol stuff? I sprayed a little in my car. It takes too long to dry. once it dries it doesn't stink, but may take a few days for the smell to go away.

So from my limited experience with the spray can stuff............... I won't use it again. Might be decent in boxes or whatever, but not in the place of a dynamat type deadener.

it wouldnt be dense enough i dont think. Pretty much the heavier the better. A spray is the opposite of heavy

The guy at circuit city was telling me dynamat has a product that comes by the gallon and you roll it on. I have not looked for it though.

People have mixed results with that. Again, drying time would be an issue. I have a gallon of that myself that I will put some use to.

What's your budget on deadener?

the less i spend on it the more i can spend on other mods. But i dont wanna WASTE my money on something that wont work. Id also like to keep it light as posible.

there are several companies who make visceolastic sound deadeners. second skin, e-dead and even dynomat make them. they will work just as good as your typical sheet-styled deadeners if you apply them correctly.

do not confuse these with bed liners or rust proofing coatings.

what would the best brand be?

I have useed cascade and I like it. Its very heavy and thats what sound deadener does well is mass load the panel. It does take a little time to dry between coats but for a trunk and floor its great. I like not having to cut strips and fart around with pressing it into corners, just pour it in and roll it out. I would still use some matt on my next car but its gunna be 80 percent liquid and some matt on the roof. The liquid sticks great I would just do the roof so I don't drip.
