Sound Deadening These Old Rattle Cans...

[hick]

Folks, once again I call your vast experience and and knowledge

I am in the planning and hoarding stages of my CCLB build. Its soul purpose is going to be a DD/work truck, this wont be a trailer queen.

While riding around in a 06 Chev Dmax today (test drive), it dawned on me that this is the truck I am modeling it after in the back of my head. I am using the drivetrain (hence the test drive), seats and likely the dash. I want every thing in this truck, just in a sqaure wrapper (i haver a way of choosing the hardest route to do things)

Now my concern is, can these old squares be made to ride as quite and comfortable as new vehicles? I don't mind spending good money on good product and i understand it wont be 100% but i want close. Now im talking smooth ride, i am strictly talking about road noise and highway comfort

I have no experience in sound deadening and hear great things about second skin and such, but i want to know just how close I can get.

Thoughts and comments are greatly appreciated,

Thank you

Scott

I used Second Skin Damplifer Pro On my crew on the doors, floor, and roof. It made a huge difference, cost was about $900 dollars but I feel it was worth every penny I was pretty impressed with their product .

Someone on here did their crew cab... Think it's dieseldawg142? Could ask him how his was. He used MLV in everything and fat mat.

Lizard skin makes 2 great products. One for sound and one for heat.

Cascade audio is one of the best for sound deadening. Also a company called Sound Deadener Showdown. You'll be spending a good bit of money like that one member said, close to $1,000 to do the job right.

I used Dynamat and love the results, I have never used anything else.

[TexasJeff]

I used FatMat, just like Dynamat but cheaper.

Awesome.

Thanks for the insight gentlemen. I will do research into the product but the general consensus seems to be that i can get this truck close to if not above and beyond modern standards.

Your comments are Much appreciated

All you need is some injectable foam, mass loaded vinyl, and peel and seal (home Depot)

I am going to have to disagree here. You can make it quieter than when it was new. You can make it ride better than when it was new. But it won't ever compare to a 2014 truck.

Just trying to manage your expectations...

Stay the hell away from that injectable foam crap. It stores moisture and will rust you truck out!

I've used FatMat and Lowes/Home Depot peel N Seel, both work pretty good.
For a higher budget build, I've used FatMat and for low buck build( which most of mine are), I've used peel and seel with very good luck and results.

you do realize most the companies use an injectable Foam In their cars and trucks, if you have a leak it will hold moisture

Injectable? How?where? Elaborate

We mainly used them to stop two panels from vibrating again each other because the bass would cause heavy vibrations

Is peel and seal that roof stuff? If so, is it asphalt based? Do not use asphalt based stuff in your truck. Especially if you live in an area where it gets hot. Very bad idea

This is the proper way to do it. It is how luxury cars are done. Look up luxuryliner

I used Dynamat Extreme on the floor and firewall but ran out and didn't do the back wall of cab or the doors. Road noise is the same as without the Dynamat.
What is this peel-n-seal stuff exactly?

[Skunksmash]

Cheap roofing repair stuff you can get at home depot. IIRC, its similar to the construction of the sound deadeners because its got black goop attached to an aluminum backing. Why I'd never use it:

1. I'd be willing to bet its asphalt based. That stuff melts a little in high heat, and its enough for it to start showing up in the seams of your carpet. Where it meets the panels and such. Seen that personally.

2. Do you like the smell of a new blacktop parking lot in high heat? Your truck's interior will now have that smell if you live in an area (like the south) where it gets hot.

3. It was never made for this purpose, and as such the aluminum is very thin. The good ones, like Dynamat Extreme for example, employ a much thicker (relatively) aluminum backing. This is the key element in "blocking" the sound as it adds the necessary mass needed to dampen the resonance of the metal. Your metal is basically vibrating as you're rolling down the road, and the thicker aluminum just won't jiggle as much and thus your metal doesn't get to make any noise. That roofing stuff was never intended for this purpose. Your best bet is just cough up a few more bucks and do it right.

I used fatmat in mine along with a new carpet kit that had the jute padding on it. Although not as quite as a new car, there are places I can improve on, it is much quieter and a normal conversation can take place.

Also, don't forget that a quiet exhaust is one of the keys to a quiet ride.

absolutely! headers, 3" exhaust & delta 50's was the main reason i did my crew. i was going to switch to big block 70's, but now that i'm deadened, i can live with the 50's

[mrolds88]

I used some of the peel and seal stuff I got at Lowes. Wasn't the aluminum backed type. It was rubber sheet with adhesive on the back. I think GAF made it. As far as the injectable foam goes, most are thinking of the Great Stuff type of foam. I believe it dries as an open cell foam. I have a truck that was used in. Yes it holds moisture. That's why it's named Rusty. I don't really like the factory foam either. GM did it in the 70's in quarter panels, etc and it created an awful lot of rust.

I bought two rolls to actually use on my roof, but turned out its not suitable for my house. As an experiment since its been 80 or so and thats as hot as it typically gets here, I left both rolls in the truck as well as a couple of sample pieces about a foot long applied to the truck.
So far a faint odor is there, keep in mind I don't have a carpet yet so its just that stuff in there. Waiting it out to see if it gets worse or not.....
