Anyone here order sound deadening material from McMaster Carr? They have a few products that look interesting, one called Peel n Seal. Seems to be similar to the Dynamat's out there.

THanks

Do you have a link to the product you are referring to? I looked on their webpage and couldnt find anything like what you are referring to.

Looks like it's on page 3397 of the online catalog. Just check the temperature rating of the adhesive... some are a little low for a car interior (like a roof)
I've ordered lots of things from McMaster-Carr and all have been top quality. Also there return policy is excellent, so even you decide the material is not right (before installing), you're not stuck with it (other than shipping)

Don't know about McMaster Carr but after countless hours of research, and postings, and more research, including a loooong article comparing all the brands, RAAMAT is what's going in my car, no question. As good or better than Dynamat and much cheaper. Best value and best performance. Will be installing it in about 8 weeks after my car comes out of paint :hurray: Do a search here and you will find a link to the article.

Ya, for the price RAAMmat is the cheepest solution without having to use you own brew.

One manufacter called MFM makes a product called "Peel n Seal" for roofing of mobile homes. Suppose to be available at your local Lowes or HD, but in CA we don't have any. 100sq ft for $90. vs 100 sq ft of Dynamat @$300-400

Remember that the tar-paper type stuff used on homes has a good chance of turning to goo in high heat. They butyl type products (dynamat, Hushmat, etc) will not.
www.sounddeadenershowdown.com has a good review of some types, but not everything that's out there.

Hard for me to understand how roofing undermat would turn to goo. I sure the temps on the roof far exceed what the car may experience.

Bryan (AKA Bowtie-72) has it right and he gave the link to the long article I was talking about. I highly recommend the reading. the guy who did the tests is totally independant from what I couold tell and used his own money to buy the products. Sold me on RAAMAT for much less than the Dynamat and it is the butyl type. Read the article it will tell you all about it.

There's a company in Texas that sells a comparable product without adhesive backing- you'd need to use 3M trim adhesive or contact cement to install it. You'll like the price. lobucrod.com I believe. At least worth checking out.

Raammat, installed 3 weeks ago.. Paid $98 for 62 sq ft and free shipping..:thumbsup:

Also possible odor when that material gets hot in summer, or just hot.

does anyone have a good suggeation on the best place to buy raamat?

can this stuff be used behind the headliner also?

You can get RAAmmat from their website, just go here..... http://www.raamaudio.com/cgi-bin/index.cgi

I got some Peel N Seel coming, i'll be comparing the two. Peel N Seel prob in the doors, and RAAMmat on the floors

Did a little more digging and found some tape that is butyl based... 45 mils with butly layer.

YEP !!!!!

I bought some edead off ebay and I really like it. I paid 250.00 for 240 sq. ft. I got 120 and my dad got the other for his car. I did the doors and from the firewall all the way to the rear package tray and i have one roll left so I will use it in the trunk floor under the carpet.

I bought a 100sq ft for $109 off ebay a while ago. I did the entire trunk and all 4 doors in my 2002 Pontiac Grand Am.

Thumbs up for RAAMMAT. I used it in my 55 and my 67 and i am in the process of doing a 68 camaro for a friend. Extremely easy to use and well made.

That's a heck of a deal...would you like to share with us where you bought it from?
Thanks,

Does putting any of these on the floor of your car have a detrimental effect on the sheet metal ?
