sound proofing

[slayer]

ok how many people have done sound proofing and what seems to work the best. i am getting 8lb house carpet padding today and i have carpeting but was thinking about sound proofing my 620 as well.

 

then it's time to find a quiet exaust.

I use Dynamat or Dynamat extreme. It applies well, insulates well, looks good (tho you never see it). I will say it is expensive and heavy, but it's the best you can do.

I used a part roll of roofing tar about 1/4-3/8" thick. It's dry and flexible and comes in a 1 meter width. You can cut easily with tin snips and even 'weld' pieces together with a propane torch, just heat and press together. It's flexible but if heated with a torch even more so and can be pressed into corners. Once in, lay your carpet. It's dry and has a plastic film on one side you peel off if heating. Talk to any roofer they'll probably give you an end roll. I did.

i'd break the piggy bank and get dynamat xtreme

 

it's pretty easy to work with; you can mold it with your fingers and hands

 

(and you'll be thankful of that by the time your done)

 

plus, it makes a HUGE difference in an old dat

 

gets rid of much road noise and tinny sounds

I'm coating the floor of the KC with bed liner from Signature spray in liners.I'm not doing this for noise,but it should have a quieting effect

JC Whitney sells what is essentially a bitumen impregnated mat by the foot. I used it to replace the factory matting under my rear seat, an exact match for factory installation. Just be sure to let it warm up and install on a sunny day. It will crack if you try to unroll on a cold day. It would be good for sound deadening inside large door panels. Under floor mats I use ordinary foam carpet padding. No fuss, no mus and it cant bleed thru.

I know it probably won't make much of a difference, but keep in mind how much these mats weigh, and how much you're using. On a car that weighs less than a ton adding even 50 lbs will make a slight difference in feel.

when you get to be our age, there's none of those left

unless you count the tweekers

[sr71sss]

to add to the discussion has anyone tried the spray on/roll on sound deadening stuff. I remember seeing some on GEARZ a few times which was called lizard skin and it looked just like tar in a bucket-probably was but it says that it comes with a special gun where you can spray it on.

The guys on my old Ford forum swear by this product. Comes in rolls 6' x 4', longer lengths by request. Reduces sound and heat very well. A specially made fiberglass insulation bonded to aluminum substrate. Very, very light. You can even use it above headliners.

 

It is sold by one of that forum's members who I think works for the manufacturer. Pricing is very good, and I believe he is nice enough to send a small sample on request.

 

He usually has some listed on ePay, but I didn't find any tonight.

 

If you are interested, send me a PM and I will give you his name and number.

somebody i know tried that stuff and said it only worked as good as dynamat if you doubled it up. im not sure about the cost difference, but just somehting to think about.

[84TAVeRT]

i figure 1 roll should do 3 or 4 layers in the 521...

 

firewall, floor, backwall, and under the door panels...

I've heard (pun intended) that Q-Pads work pretty good:

 

.

 

I also believe they're cheaper than Dynamat.

yeah, I've used those. A lot cheaper than dynamat but you have to kind of heat it up to get it to stay and form to where you are sticking it.

 

 

Also a little hard to find locally. A friend happen to know a store but most places I went had no idea what I was talking about and tried to sell me dynamat. :rolleyes:

Well, the person who recommended them lives in Arizona. Even then, they warmed 'em with a torch to mold 'em into place.

 

I haven't looked for 'em in Washington, yet.

I used fat mat in my '92 mazda, it made a difference. I don't have a dyna matted vehicle to compair it too though.

[dat521kid]

has anyone tried to spray any of that under the hood? mines is pretty beat up and i think it will make it look good but i want feedback, thanks.

[sdsurf]

I was thinking of a roll on liquid applied waterproof membrane by tremco called 201. You can build up the mils and it says flexible...

I can get it cheap which is why I may try... Albeit - very very permanent...

[dat521kid]

hey sdsurf, is that for under the hood? if yes, is it flamable?

[sdsurf]

i wouldn't use under hood... i would use as sound proofing on th floor boards and other cab areas

[dat521kid]

darn.. im looking for something under the hood, any suggestions or am i just crazy?
