Choosing the better Sound Deadner, Help?

[WorldsLoudestCreature]

I'm looking at getting 100 sheets of either one if these to do my entire truck or most of it anyways. Trying to reduce rattling and maybe sealing my car up better so temperatures from outside don't leak in our out. Which would be better? All in all? Thanks.

Sound deadener won't do much for temperature. They make specific foam products for that which you would lay on top of your sound deadener.

Honestly dont care about tempature that much, just trying to get the best Sound Deadening Product ? Anybody, m, from these two choices ?

I'm a Second Skin guy myself but that's just my preference
You might be off with how much you need. 100 sheets seems like a lot but I'm not sure how big your truck is.
If you scroll down to the bottom of the page there is a calculator for square footage .

One tip I can give you is those little wooden rollers ****. Go to a hardware store and get a wallpaper roller

I also use secondskin. Goes on sale often, or email them and ask nicely for a discount code. Resonix is also well regarded, but Ive never used it.

I used Rockville and I'm happy with the results. It's cheap and it's butyl.

For best results (imo): I recommend applying some Ampere Vibraflex on all flimsy parts like the roof, doors, fenders/quarter panels and under the seats. Then you put a layer of butyl over it and the rest of your vehicle.

Damplifier smells for a while but is the most effective butyl I've used.

I thought it's not supposed to smell if it's butyl.

TLDR. SDS was the best deadener. They are no longer in business. IIRC Resonix CLD is now the recommended deadener. The owner is on here.

Don't do your entire car and don't do 100 sheets (waste of money). Full coverage comes from the myth that deadener blocks sound which is doesn't. It helps prevent the panels from vibrating (reasonance) but it doesn't actually block noise. Most people think "oh if I do full coverage i'll block the noise from coming it" when it doesn't work like that. You need something like MLV

For most high quality deadenders 25-40% coverage is more than enough. You eventually get to the point of diminishing returns. Think of it like a drum cymbal, if I apply 25% coverage to the cymbal and then hit it with the drum stick the cymbal will hardly make any noise. Me adding 75% more coverage to that same cymbal might make it 5% quitier if even that

Ok, I was just playing around on amazon and found this

Has anyone tried this?

Damp pro smells a little, goes away pretty quickly. I think its the adhesive that smells.
