Interior Insulation and Sound Deadening
I'm ready to add some insulation to the interior and wanted your thoughts about the self-adhesive type products out there. Just looking at various installations, it looks like this is a on-time shot, and the next guy that wants to restore or repair something is going to have a hell of a time getting the stuff off. Dynamat, GTmat, Fatmat, etc. Spray glued jute will at least come off with some elbow grease.
So what do you think? Just go for it since it's likely I'll never have to deal with it again, or to have pity for the next poor bastage that restores this car again some 40 years from now (assuming a solar flare doesn't bring the grid down, but that's another story)?
I'm thinking go for the better technology. I already ripped out that disaster of a firewall insulation kit and threw it in the trash in complete frustration, so now I'll need recommendations. I'm not paying Dynamat's prices, so might as well stow that info. Also, some of these products are offered in various thicknesses, such as 50mil and 80mil. Any advantage to thicker? How about the stuff from Lowe's (Reflectix)? Oh, and if it has 'any' lingering odor, I'm not interested.
Tnx!

I posted a thread on this topic a while ago and didn't get much response. I like the spray on Lizard Skin treatment. They have a 2 step process with one application for heat insulation and the other as a sound deadener. Only problem is that I am in Australia and the Australian distributor wants $600 for the kit to do it. I would be interested what the kit retails for in the US though. The spray on products appeal to me over the stick on (Dynamat type) of products as they would seal off the steel from moisture, whereas the stick on products may allow moisture in between the product and the metal promoting corrosion.
Cheers, Colin

go for it since it's likely I'll never have to deal with it again, or to have pity for the next poor bastage that restores this car again some 40 years from now How old will you be 40 years from now, and by then.... will you care?
I'll need recommendations. I'm not paying Dynamat's prices, I used FatMat.... same type of stuff as Dynamat at a fraction of the cost
How about the stuff from Lowe's (Reflectix)?
I put Reflectix on top of the FatMat. From what I`ve read on these boards, one is more for heat, the other for sound. Carpet went in over it just fine.

You can get the dynamat pretty cheap off ebay or amazon, it's only expensive at retail stores. I think mine was $120 for enough to do the whole car...that's not much in the grand scheme of things.

I used Cool It from NAPA. It was an easy install and works well. I scrubbed first with hot soapy water then wiped the fiberglass down with lacquer thinner, it stuck really well.

oldgto... I haven't seen Reflectix live. Are those air bubbles, like in packing material? That looks like a decent combo you're running.
Colin... I just heard of a "new" product called Henry's Radiant Barrier. It's supposed to be a coating system as well. I'll have to look it up. No sure I want to spray anything at thing stage, tho.
edit... never mind on that Henry's stuff. Guess the HD people didn't understand my question.

So let's say I've (you've) figured out that I need some hi-tech stickum stuff everywhere. After that, what are you all doing for carpet padding?

OMG, can you pop the bubbles? I worried about that when I first bought it, but it didn`t seem to happen, even with me crawling all over it, and putting my knees down on it during the installation.

Also, be aware of the area around the accelerator pedal. It's easy to have material build-up in the compound angle there, and may cause issues with the pedal sticking or not getting full throttle. Not much room down there to begin with.

I bought my Dynamat from Amazon but it was for my C6. I plan to do the same for my '81. I also did my S10 with it but haven't driven it yet with it in there.

Was considering putting Dynamat over top of this.

I settled on a couple RAAMaudio products for what I need now, and that's the firewall and under dash areas so I can start installing components. I'm holding off on the other interior areas until I'm near completion so I don't screw up the backing. It sure will be nice to have stuff hanging in there again.
I got the BXT II RAAMmat, and Ensolite. I'll layer the Ensolite right over the mat. That should take care of both heat and noise. So if y'all aren't doing anything, c'mon over and teach me (by example) of how to do this!

Fatmat is same as Dynamat but less expensive, they offer a thicker version as well as offer it with no logo on it. Ebay
I think Frost King from Lowes is nice over the Fatmat with its easy to use self adhesive backing to stick it on.

Here's my bit of a start. Having never used this stuff before, it was a lesson on how heavy the material is, and how much beer I'm going to have to consume to get through this project! And then I've got to go back over the mat with the adhesive backed Ensolite foam. Fun fun fun.

I have a question about the Reflectix - How many rolls did you use/size and - a big and - is there ANY (whatsoever) noise generated from the stuff once it is installed? I noticed that the stuff is sort of noisy from the thin foil/plastic bubble interaction when you handle it in the store. The illustrations on the package show it being stapled to an external house wall during renovation. I imagine it is effective at insulating (assuming the little bubbles hold up in that environment over the years) but moreso wonder about any noise it emits in the slightest even with the jute backing and carpet over it in yours, or anyone's experience? It always comes up as an option, but just ask'n

I used a product called Stinger Roadkill. Pretty much the exact same thing as Dynamat, but a lot less in price. Took about a box and a half and that did the floorboards from front to up around the tail lights in back and both doors. My ONLY complaint is I know I've added close to 40 pounds to my car, but I'd bet it's much cooler inside and much quieter as well.
