carpet underlayment
Just finishing up a frame off restoration on my 76. I am looking to put some kind of sound deadener under carpet. A vette place i deal with said to just go to home depot and buy the thin foil like insulation they have there. I looked at it and it looks pretty good for a fraction of the cost of some of the online stuff performance stuff. Anyone ever use it or have any luck with it. thanks

I was all ready to buy a kit of the foil heat barrier at Carlisle this year. A lady working a booth that sold carpet told me to just get the stuff at Home Depot and save a bundle of cash. I have bought it, and I bought 3M carpet/trim adhesive, but I have have had no time to try installing it yet. I hope to over the holiday weekend.

Maybe I am wrong but you said that you are looking for SOUND deadener. I think the foil at home depot that you are talking about is for heat but won't do much for sound. I plan on using the jute and the foil together.

I put second skin all over in my car but then I was at Menards and saw
Reflectix on sale for $15 and thought what the hell, it can't hurt. I put a layer of it over the second skin. It is very thin and light and cheap. It was very easy to install. Spray adhesive, aluminum tape and you are good.

I initially bought a 16" x 25' roll of Reflectix from Home Depot (like others said, it was less than $20) to do the floorboards up to the firewall, as well as the rear storage compartment. I ended up having to buy a second roll to finish the job, though.
I started the project thinking I'd affix the Reflectix to the body with spray adhesive. I abandoned that quickly, though, after deciding that I didn't want to have to hold the Reflectix in place while I waited for glue to dry. Instead, I put strips of Gorilla tape down (black), followed by the heaviest duty double-sided tape I could find (see first photo...its the red outer layer), to which I then affixed the Reflectix. That technique worked well throughout the car; I recently installed the carpet in the rear storage compartment, and it fits nicely. I am going to have to fool with the fit in the driver and passenger seats, though; perhaps the Reflectix has disrupted the fit despite its being only 1/4" thick.
After a couple of test drives without carpet, it seems that the Gorilla tape/double sided tape/Reflectix combo will serve its intended purpose.

I wound up using 3M77. Spray both surfaces (floor and also foil), wait a few second and lay it in. I have not laid the carpet in so I don't know if it will interfere with it or not, but the stuff is pretty thin so I hope I will be okay.

I used 2 rolls or reflectix, 1 roll was just not enough for the complete interior,
I also made door liners out of the same stuff.
can't beat the price, there are better underlayment products avaliable , but not cheaper.

Russ: I needed more than the 1 roll of the 16" wide for front and back. I didn't try the 3M spray adhesive since I was concerned about exceeding the max temperature (per the instructions on the can...I think it told me not to exceed 120 degrees F), especially in the vicinity of the firewall. Maybe 3M sells some "high temperature" spray adhesive, but I just never looked into it.
