reducing sound in the interior

[Spartan]

I had some good feedback on the topic a while back but when XP vapor locked I lost all my info.  Does anyone have any info on where to get sound deadening material to quiet down the inside of the car? and how do you work it around the gas pedal and center console?  Now that equipment install season is over I would like to finally work on the old girl while there is still summer left.  Thanks.

you can use a ceramic Foam it work great & is very light , you have to brush it on & it drys quick , I can get a Manufacturer for it if needed

Will this product reduce heat in the interior as well?

I see that many of the TV shows doing restorations use Dynomat.  Anyone ever used that before?

[Silver R/T]

one word for you...Dynamat

[Troy]

Dynomat is heavy and expensive for what you get - although it does deaden the sound. The first thing to check is to seal all the air gaps. You can get generic sound deadener or use the newer ceramic coatings. The ceramic coatings also act as a heat barrier and are chip resistant so you get extra benefits.

well its kinda heavy ya, if youre 'ricer' and concerned about few extra lbs, but if you want quiet charger thatll do the trick, depending on where you buy it from you can get it reasonably cheap. best bet is to have buddy from like best buy etc.

[MadScientist]

Can Dynamat go above the headliner?  If not, what else can be used?

You *can* use that stuff that looks like bubble wrap with a silver lining. It's cheap, incredibly light, resists heat, and does a fairly good job with noise suppression. There was also factory insulation glued up there which should work pretty well. I wouldn't hang Dynamat from the roof but it's your car.

Apparently certain people have never picked up an entire roll of Dynamat. Go do that before buying it. (I suppose only "ricers" really care about weight reduction in the real world.) Also, check for the alternatives just in case you don't have a loser friend working at Best Buy. It's something close to the consistency of tar paper, a pain to cut/shape, does not follow contours very well, can't be painted or reasonably covered, and costs way more than it should. You can buy the exact same thing as an off-brand ands save a ton of money if you can deal with the drawbacks. Everything has it's place but don't let that stop you from investigating alternatives.

I bought a roll of insulation/sound deadener from JC Whitney. Cost 30 some dollars for a 5 or 6 foot roll. It has a foil backing and is supposed to resist mold. I originally used it to replace the rotted insulation inside my heater/AC box but I'm also going to use what's left over inside of my door panels. I bought the headliner insulation from Jim's but all that really turned out to be was that white floss looking stuff like I've seen people use as packing material.

yes it inslualted heat as well as sound

[runningman]

chryco, you have a name/manufacturer for that stuff?

[Troy]

One of the brand names (I think what Chryco is talking about too) is Lizard Skin or Cool Car. It is a I have some links at home but you're basically looking for ceramic foam coating.

Here's some links that I just found (Google: Latex Ceramic Insulation Coating)

Dynamat apparently now makes a sprayable/brushable coating but it isn't ceramic and I know nothing about it.

Troy, thanks.  That stuff seems pretty interesting.  I will check it out.  Matt

Yeah, very interesting

I restored a 69 RR a few years back. The owner had Dynomat installed all over that car. When he brought the car from that shop back to mine. It had come down from the roof and started to come off of the inside of the 1/4s. He took it back 3 times. It never work for him. We ended up using the bubble wrap with foil on both sides. Its very cheap, you can get it at any home improvement store and its very light so it stays where you put it. You have to glue it in place.

I have been looking at the new ceramic stile of insulating. If your not worried about the price then I belive that this is the way to go. I went to a rod show here in town about two years ago. There was a ceramic type that you sprayed on and you could put it on up to 1/4 in thick. They had it on an electic skilet. !/2 of it was left alone and the other have had it on. The skilet was turned all the way up. You could touch the area that had the coating on and couldn't feel any heat. He would put an ice cube on it and it would melt very slowly. Then he would put an ice cube on the unprotected side and it would melt and sizzle away really quick. I talked to another guy that had a Willies with a 426 blown Hemi. The exhaust went right under his feet. He said he tried everything but his feet got so hot he couldn't drive it. He put this same stuff on the floor bord and he can now drive the car with out any shoes and not feel any heat.

[Drop Top]

Forgot to mention. He also said it helped reduce the sound tremendously. He sprayed the entire inside of the car with it. I sat in the car with the doors closed,widows up. We had a very nice conversation with out having to yell at each other. The car had duel 3" exhaust with Dydomax mufflers. Very loud on the outside.

You can get sound deadening material that fits a specific car from auto custom carpets: http://www.accmats.com/products/Sound/sound.htm

I used the bubble wrap with foil both sides in the Chally, and it works ok.  For the Charger, I got some stuff from JCW that looks like carpet pad jute with foil on both sides and I like it better.  In both cars I've got it on the roof, floor under carpet, doors, qutrs, trunk divider firewall, and anywhere else I could manage to find a place for it.  THEN I taped up all the seams with alum tape.  Think I got a pic somewhere...

Sorry to dredge this thread up but I've always wondered how people get the rear seat back in this this stuff on the floor. It's such a major PITA to get it in w/o a thicker floor it would seem impossible with.

[dkn1997]

Do a search for "Ramaat"  I got a ton of info from the guy who sells it and there is also a sound deadener shoot out floating around somewhere on the web.  use a butyl based (ie: NOT dynamat) sound deadener.  dynamat and many others are ashpault based and have a low melting point, contributing to the "falling down" described above.  I believe Dynamat extreme is butyl based, but many many bucks. 

email the guy from ramaat, he will respond with at least a page on your particular car.

this one?

[dkn1997]

That's the one.  and it's Raamat, not Ramaat like i said before.  If I had a scanner, i would show you the detailed info he gave me on doing a big car like a charger.  He really took a lot of time

The weights of these various methods of sound deadening aren't an upside/downside of a particular brand, they're a necessary compromise so the stuff can work.

You can kill higher frequency noises with lots of air gaps in the material and that can remain pretty light.  But the only way to really bring down low-frequency droning noise is to put a lot of mass in front of it.    I think this is still true no matter what you make the stuff out of. 


The factory sound-deadening on modern cars is still a pretty heavy layer the last time I looked into it.  And the OEMs are so weight-happy that they surely would have found a better solution if it was out there.

[tomdroptop]

I went & searched that link & he has a kit made just for Chargers but If/when I go that route I will prob need to buy more so I can do the doors & roof.
