Barry, kind sole that he is sent me a couple of peices of the good sound and heat insulating stuff for my doors.

To cool to install yet but I am so impressed I am going to do Miss Agathas cave, the floor anyway and the wheel wells.

Expensive, yep, looks like the real answer to noise and heat from what I see.
 
Jack, can you enighten us on how to properly install the sound deadening stuff? I hear that unless it's glued down very firmly, condensation/moisure may form and cause rust.

I put a lot of the stuff in cars before with no problemo. But others have experienced rust.

What's the deal?
 
Aye, Dynamat. It has a peal off paper back with black sticky stuff under it. The outer surface is alum, soft but heavy.

I don't see how it could not stick if the surface was clean.

There should be no space between the product and the metal, don't see how condensation could get in there.
 
If you can't wait until it warms up a little, sneak the wifes hair dryer out of the bathroom when she's not looking and use it to warm up the metal. You'd be surprized how much condensation will appear when the heat from the hair dryer hits the paint. Oh BTW: the backing paper will come off better if the mat is room tempeture.
 
Well, you knew I could not wait. Drivers side door finished. Super stick stuff, really makes the door sound good when closing.
 
/bcforum/images/%%GRAEMLIN_URL%%/thumbsup.gif Good for you Jack! I love the stuff and knew you would too. Truly world-class stuff. I can't believe how much resonating sound it eliminates. I did the entire cockpit area, under carpet, and when I started the car there is NO noise. I mean, all I can hear is the exhaust! Can't wait to get her on the road and see how much road noise is squashed. The claims are to eliminate heat as well. If it works half as well on the heat issue as it does with sound I will be happy! Here is the link if anyone is interested. It is called second skin. A bit cheaper than dyno mat. SOmeone on here lead me to the stuff, sorry I can't remember who. It took 40 square and I had a bit left to send to Jack.
 
I think John used it in his MGB.
 
Has anyone used the spray-on product, Dead Skin? My son left me a can of it and I was wondering how good/effective it is vs. Dynamat!
 
The only Dead Skin I've seen is in mat form. Does it have a petroleum smell?
 
It's great for heat reduction. I put it in my 100-6 and couldn't beleive the difference.

One question - has anybody tried to remove this stuff?
 
Both sides in now. What it does for door closing is nothing short of out of this world. Sounds like a Cadilac.
 
I have not used Dynamat, but last summer I did a complete install (78 Midget) with B-Quiet. It is wonderful stuff. Huge difference in noise reduction. I can actually hear the radio.

Removed all carpet and pannels. Removed OEM sound damper from tunnel and foot wells. Scrubed very clean; very happy w/ no rust. Had a little bubbled paint below drivers heals and seat rail contact points; hand sanded clean, treated w/ rust stop, primered and rattle can top coat for more seal. B-Quiet rolled on extreamly well. Molds easy to irregularities on floor and covers comples curves. Covered 100% of interior metal. Much noise comes from firewalls.

B-Quiet is visually similar to Dynamat. Easily pealed paper; a layer of a black tar-like material that sticks very well to clean dry surface; topped with a layer of very thick tin foil. Suggest going to web sites for both products. I was surprised to find both companies show certification test results to ASTM E756 at 200 HZ. B-Quiet.com has a Comparison page that shows their product is slightly lighter, slightly thinner, and is slightly better accoustically than Dynamat, yet it is less than half the price. I was skepticable. I was also surprises to see Dynamat used the same numbers in their tech data.

I am now a believer. Cost for 50 sq ft is $130 plus shipping from factory.
