I have a noisy diesel jetta. I would like to add extra or
better dampening material, i figure something very dense (tar
or wax saturated) would do.
Does anyone know of a material that can be used.

As silly as it sounds… use a few layers of mouse pads. Make
sure they are the "wet suit" type. These worked very well in
our Cabriolet. They don’t absorb water and they are cheap!!

I’m sending you my original post on some sound deadening stuff. Since
then I’ve read some posts about this new wave of sound deadening
material simply being the equivalent of roofing paper. I’ve worked
with roofing paper, and it ain’t the same, but it is possible that there
are other kinds of roofing supplies that work just as well (for all I know).
Stinger recently put a sound deadening material on the market for
about $70 for 6 sq. ft. which is much lower than Dynamat or the other
guys. My stuff lists for $50 for about (I think I figured it as) 12 sq. ft.
Hope this help.
Jud.
Here goes:
I had a couple requests for this…
It’s made by 3M, called "Silence Strips," part no. 051135 08585. Each box
contains 1 roll of 3" wide x 50′ long strips, with a removable backing on
one side and a plastic covering on the other. Thickness is about 1/32" to
1/16" (sorry, no calipers on hand). That equals 12.5 sq. ft. of area that
you can cover with one box. Price was $50.00/box about a year ago.
Application is made by first cleaning the area first, then removing the
backing and pressing in place.
It has produced no smells at all.
There was no address on the box at all, so I’m giving you the phone #
of the guy who turned me on to this stuff (who also did my car audio
install and SHAMELESS PLUG did a great job at that, too).
Randall Miller
Mark Troxell
Sparkys Supply
1-800-845-9473
Denver metro: 781-5222
With six boxes I covered the entire floorplan of my 80 Scirocco, including
the spare tire well, the entire space behind the panels besides the rear
seat (I fabricated a walnut panel and used the area behind as a speaker
enclosure for my Kef 6x9s), both doors, up to and behind the dash, and
even the area between the cabin and the engine bay where the vents and
windshield wiper motor and electronics is.
Needless to say, the hardest part of all this was getting everything out
of the way and then cleaning (and cleaning, and cleaning, and…) the
sucker of 14 years worth of dirt and grime.
When I saw I did the floor plan and doors and so on, I mean I stuck as
much soundproofing as I possible could fit. The nice thing about this
stuff is that you just pull out of an opening the length of the strip that
you want and cut – so it’s easy to get the amount you want.
I’d recommend doing this when it’s over 70 Fahrenheit.
Oh, wait, I just found an address on the box:
3M Adhesives
Coatings and Sealers Division
St. Paul, MN 55144-1000
612-733-1110 (Operator #55).
It works very well, and I’m running polyurethane bushings everywhere
except for the front and rear motor mounts (hard rubber). And now that
I have an exhaust that FITS (as opposed to what I got from Techtonics)
I won’t have the exhaust rattling against my damn gas tank (and yes, it
was properly installed, and all of the tricks were done).
I have noticed that now I can hear that I need new door and rear hatch
rubber (getting wind noise). But that’s easy to do in comparison.
One final note. Even with the ease of installing this stuff, I will tell you
that it is a royal pain in the ass and a lot of work. But for my ears (they
are especially design to trap and hold in water – as I found during my
many ear infection youth), since I have some tinitis, I need it.
And a warning for all you hard rockers out there. I have a friend who,
still in his 20s, is going deaf ’cause he cranked the amp up one too many
times. I’m not your mommy, you can do what you want, but despite
the whining and annoying tone of those who are always telling you what
to do (including our federal government), this is real. It is a problem.
Just ask Pete Townshend.
Enjoy this stuff. It works very well, and it’s gotta be a quarter of the
cost of Dynamat (and hey, this is 3M, I wonder where Dynamat and the
others came up with this stuff. Could it be they licensed the patent from
3M and are ripping everyone else off to the tune of 400% profits???)

FWIW, I recently downloaded and read the rec.audio.car FAQ and roofing
stuff is called "Ice Gard," I think. Supposedly, it’s similar in
character and thickness to Dynamat and even has peel-’n-stick adhesive on
one side. The price was about $70 per 250 sq ft. The downside was that,
unless you could get scraps from a roofer, you had to purchase a whole 250
sqft roll. I suspect that my chances of finding a product called "Ice
Gard" at the local building supply businesses here in Missisisippi are
poor to none
