I dont want to use that cheap asphalt type of sound matting at the hardware store, I want butyle based with a foil back, so whats the best deal right now?

Dynamat is overpriced so thats out, I only need about 10SF to do my new doors and whatever is left over will get stuck on the floor.
 
Don't know if they're the cheapest but I bought damplifier for my car:

It also comes in black foil which i used on my inner firewall where it would show above the carpet line. Once I bought some they sent emails of discount 'B stock' and bought some of it in silver for the hidden areas.
Get a decent roller at a local sewing shop or cooking place, their roller was wood with two nails in it, nails fell out on first use, couldn't put any pressure on it, I need to find an all metal one. Other wise easy to cut with $2 shop scissors from HF or a straight edge and razor knife.

check out those small rollers at home depot/lowes for installing window screen. thats what i use for insulation & interior upholstery material..
 
Are you talking about the thin ones for pushing into corners/ crevaces like this?

I was looking for a better roller, like this maybe:

This is what they sold me for $10-$15, they ought to throw it in for orders over ~$50...

the one i had (it got crispy) was similar to the second one. pretty sure i got it in the screen section. could always bring that one you have by when your here & we could bulletproof it...
 
I see Fatmat on Ebay, 50 SF for $90 or the same thing in "No logo" for $25 for 10SF.

I guess I could spend the $90 but I really did not plan on lining the interior with it, but its cheaper per SF to buy more.

I could make a roller, or improve that one I guess. (Or not even use one?)
 
I used the fatmat to start out with. I wish I would have done a little more research before I did. What I read was the fatmat that I bought is pretty much the same stuff you get at Home Depot, it's asphalt based that has the black tar like substance.

I used this product after I spent so time researching on the Internet. It's butyle based.

www.raamaudio.com

If you do a search on the Internet, there is tons of info on this subject. There are other threads on this site on this as well.

I used a nice linoleum roller that my father in-law had and a tennis ball. Those wooden rollers are crap.

If you are not in a hurry, I will probably end up with extra material as the box that I bought was not quite enough to finish the car so, I just ordered another.

I imagine if you just need enough to do the doors I might have enough left over when I am done. Like I said though, it might be a couple weeks until I know exactly what I have left over.
 
It seemed to me in any application the roller was useful, if I just stuck it on it looked like it was laying on top but when I rolled it you could see any shapes underneath it which gave me more of a bonded look so it was 'at one' with the metal to deaden sound transmission/temp. The roller really came in handy for compound surfaces like the inserts on the firewall that were indentions in the metal at 45* otherwise there would be air pockets and I had to cut the piece in half so it could mold to no more than 3 compound angles at a time without tearing the foil.

I could bring the roller by Steve but to fix it I think you'd need to make it crispy like yours...
I have a feeling if we improve the nails then the wood roller would probably split...

It's hard to tell from the pic in my sig but, the accents were actually Rootbeer brown and the car was a light faded primer. That looks pretty close though. Where was that pic taken?
 
Franklin Indiana. That car had a blue deluxe interior and disk brakes, no GT option. It was a 67. I wish I had kept a pic of the VIN.

I had that car my senior year, it was a good year. Had to sell it a few years later to get down payment money for a house since I found a girl to marry me n all. :yah .
 
For sure not the same car then, mine lived in Cali it's whole life until I bought it. That would have been cool if it just happened to be the same car though.
 
I used the fatmat xtreme that you see on ebay. The xtreme is a few mils thicker and worked great. I tried using the rollers to apply the liner ,but found using a shop rag and while rubbing and applying pressure it seemed to look more even & cleaner. I was able to get into the crevices and ridges better also. Once applied the stuff isn't releasing without applying some sort of heat to it.
 
I am finding that the FATMAT is not actually butyl based, have any of you guys that have used it had any smell issues from it being asphalt based?

Why yes , now that you mention it. Or it could be just my rear tires smokin' LOL.
 
Hmm, my concern is that if its just asphalt based then I can get it at Home Depot for a hella lot less and get the same density in my doors.
I would rather use Butyl and I guess I am looking for the cheapest way out for the butyl based stuff and then I will buy enough to do the floors while the car is going back together after paint next weekend.
 
I have used Dynamat since 1988 when I installed my first stereo system. I have used it in every car since. Fatmat and the others are cheaper for a reason. If you check most car audio forums you will the that the other brands do not compare to Dynamat.

You can get the Dynamat door kit from Amazon at a good price. Usually $40-$50 bucks. I did both my doors and the package tray with some left over. For the floors I used some older Dynamat that I had left over from about 1989! Then just use a $2 wallpaper seam roller for the install. Also a putty knife works well for the crevices.

Do you mean the Frost king duct insulation rolls?
http://www.lowes.com/pd_28929-1410-FV51 ... facetInfo=

The package or website doesn't say if they're butyl but it is a gray closed cell foam. That is a cheap way to do floors or other horizontal bottom surfaces. I tried attaching it to a clean and sealed inner firewall. The glue isn't strong so I sprayed floor and mat with 3M super adhesive and waited a day, peeled off easily still, that is the only problem with the FrostKing stuff it won't stick well or long I'm afraid. To save cost I will probably use it on the floor and trunk floor. Won't be using it on the roof, last thing I need is a new headliner with foam sagging in it. I'd avoid the doors too, I could see it falling into the window mechanism and sitting at the bottom of the door blocking the drains.
