what would be your pick of the bunch for sound deadening? at the moment im heading towards brown bread. i seem to be getting rattles beneath the body of the car(below the boot area. if i s/d the floor of the boot will it prevent other rattles occuring beneath the floor? i can't think of any other way to fix this! :?

ps. it doesn't seem that the actuall boot floor is rattling but whatever is under there.

G-Spot Serenity Max.

agreed. G-spot serenity max is the best value SDer i've used. i also have flashtac (roofing tape) and brown bread in my car, but neither are as thick/dense. taking value into consideration (wt and m^2 per $$), G-spot is great.

the actual best quality product i've used would be dynamat xtreme, but this is costly and not greatly better than serenity max.

Does it have the asphalt smell?

Whatabout Dynamat Heavy Duty...

[Adrian345]

i use dynamat extreme for my boot and doors and it works very well!

It is a bit more expensive but you can generally screw them down to give you a good price.

I use Bostik in my car and it works well.
All you are doing is adding weight to the offending panels so it really doesn't matter what you use.
I don't think there is any difference really (unless you are concerned about the smell)
I think the Dynamat Xtreme works best in really hot areas, as some of the others have adhesives that aren't up to the task on hot days and the sheets fall off!
CSR Readymix is another good one, it can b a little heavy sometimes though! LOL (This is concrete)

From what i can understand some deadeners works by converting the vibrating/ sound energy to heat energy

[HISPL]

Hmm, Viscoelastic spray on sound deadener like the Rockford spray on stuff.

Yes it converts vibrations to low level heat.

Tuneman has used some in his car.

Forgot that it even existed for a while there.

[BlackRain]

I'm using it in my car at the moment.
It doesn't have any smell..and it works well.

[Ignition22]

i was under the impression that dynamat extreme was unique as the only deadener that converts sound to heat and that all otheres add weight to reduce resonant frequency.

dont know what u guys pay for it but its around $450nz for 36sqft here

[Cyberpunky]

there are 3 possibilitys to stop or reduce resonance.

1 convert to heat
2 add mass and so given same energy is aplied, it will resonate at a lower freq, hopefully below audibilty
3 Brace. If it cant move it cant resonate.

Many deadners use a combination of the above methods.
roadkill, brown bread basically add mass

roadkill pro, dynamat extreme convert some energy to heat, brace slightly and add a slight mass

RF noisekiller blue, sound off etc mostly convert to heat.

I prefer dynamatt extreme/roadkill pro or noisekiller blue types, as they have least weight to effectivness ratio, and they stick regardless of heat issues. As my car feels every bit of weight added, having light but effective SDing is important to me.

I prefer to use roadkill pro, as its great to work with. on easy access areas like floors internal door skin etc, but prefer spray on/scrap on, in hard to reach places like inside doors, rear gaurds etc.
