Your local lumber company should have a roll for under $30. If not Lowes has a real small roll 6"x25' it's only $12.47. I figured I would try it this spring when the stuff is more plyable. Leave the windows down and no interior in it for a week or so...just in case.

Well the home depot stuff is around $40.. Fatmat is around $100 for enough to do your car and part of another car.. When I said $50 I was not thinking about shipping (i get it locally)..

Do you have a pic of this stuff? As stated I heard there is a smell issue because of the material they used in making it. I wasn't trying to be a jerk, I was just saying in the grand scheme of building a car $50-$70 is not a a lot. I guess I would have to see the home depot stuff.

One thing is true.. Dynamat and Fatmat sure are not complicated products so I wouldn't be surprised if there was something similar..

I get all my junk like this from Ebay.. one seller there is in Los Angeles so that's a drive and pick up deal.

I did not take it as you being a jerk, you bring up a very good point...you get what you pay for and sometimes being a tightwad will cause you to end up spending more in the long run or doing more work... like pulling the stinky stuff out and doing it right with the real Dynamat. Sometimes in my neverending quest to be as much a tightwad as possible I forget that and get stung! However, I've done pretty well a few times too. The ultimate tightwad and what I'm striving to be is the guy who goes to the Home insulation company that makes the stuff and gets an unlimited bulk buy of $10-$15 for 100 sq ft. has another company print up some boxes with a catchy name like FatMat, DEF-MAT, BlingMat, TUNERJiveMat or whatever with Bikini babes holding BIG WOOFERS on the cover and then sells it to all these Tuner heads at $199 per/100sqft. Then kicks back a few years later in his mansion with a 10 car garage full of nice rides. Hey I can dream can't I!

**Steve1968LS2** · 03-03-2005

TUNERjivemat.. I like that name.. hmmmm

;)

**69Rathead** · 03-03-2005

Thanks Todd. I'm going to go check it out this weekend at Lowes. Think i'll buy the small roll, unpeel it and leave it in the car for a week and see what happens...if it wreaks we'll know it. It's called peal 'n' seal right?

dennis68 · 03-03-2005

Anybody have any ideas about how well the budget stuff from "the depot" is about sound deadening. I have the luxury of living where the temp is never too cold or too hot so insulation isn't a real concern but I would love to quiet down the interior drone a bit.

That is one of the concerns brought up earlier in the thread is wether or not the sound factor could be matched with these products. If you read some of what the other guys found out you will see that the peal 'n' seal has suspiciously the same part number on it as FatMat which claims to be better or as good as Dynamat in sound deadening. If in fact it is the same stuff then we have a cheap good sound deadening alternative to use. However, if it is not the same then your guess is as good as anyone else's and we might as well just fork out the money and go with Dynamat. Basically we have several factors to consider Price, Sound, Odor and possibly vendor issues (Fatmat). I'm going to try to buy some of this stuff and check it out for Odor and see if I can take some pics and see if we can in fact verify it is really the same stuff as FatMat. It would not surprise me if it was as i'm sure someone has gone out and tried to make money by selling a "Home" insulating product as a "Audio" product. Hopefully we'll know in a week or so if it is the same.

**Tom Welch** · 03-04-2005

This is another area that screams for side by side testing of various products to determine just what is what. I want to believe that Dynomat and the various other brand names that we all know are far and away the best stuff available, but is it? I want an in depth investigation. If my find at Home Depot is the same then shame on the companies that market a way overpriced product and HOOAH! for us that have found some less expensive alternatives. The search for the truth continues...

dennis68 · 03-06-2005

OK, I broke down and bought some of the Home Depot stuff. It was 18.00 for a roll 6" wide X around 30'. The one roll covered the floor of my cab with some left over. It is about 75* outside and it's been sitting in the sun all day. When I first rolled it out at about noon today there was some odor, not asphault but something for sure. It didn't have any smell for the 2 days it sat in truck so don't think it won't smell once unrolled. After a couple hours in the sun there is nothing terribly stinky but it does smell like something. I'll update tonight after having all afternoon to heat up.

**king67rsss** · 03-06-2005

What was the name of the Home Depot stuff? I stopped by there today and couldn't find it.

**69Rathead** · 03-06-2005

Also what part number is on the stuff so we can compare it to FatMat part number...you bought the Peal 'n' seal right?

**TonyL** · 03-06-2005

Here's a bunch of "peel and seal

as a window intaller, we used it all the time around window is stucco houses. Very sticky, low odor, seemed exactly like dynamat to me, I'd used both products.

**WS6** · 03-06-2005

i just did this to my formula. i used b-quiet extreme and jute padding. you know the stuf that lays under carpets in a house. the cars quiet now. i still need to do the doors though. jute backing is great stuff, very cheap very very effective, but its not the same as any of these asphalt based products(dynomat, b-quiet, rammat). so use it in conjunction with a asphalt based stuff and youll queit the car down big time. dynomat and the like stop vibrations and jute backing absorbs noises.

brown bread from b-queit is no longer availible its now called ultimate and is a little different. still great though.

quiet ride is expensive, very exspensive. everything is precut and desinged to fit a certain way. i have never worked with precut or made to fit stuff that fit as well as their stuff did. very good quality, but like mentioned its very expensive. as for how well it works. i cant say i never rode in the car, but it should work very well. its basically the same thing i did to my car and that worked great.

dennis68 · 03-06-2005

The Home Depot stuff was called "Jiffy Seal". After sitting all day in the sun with the windows up it had a slight odor of fresh paved asphault when I sat down, it was gone after a few seconds of having the door opened. We'll see how it is by the end of the week.

**69Rathead** · 03-06-2005

Tony Thanks for the post and input! Today was my first day off and I slept all day (work nights). So Tomorrow or Tuesday I'll go get some of the stuff as well and give it a try. So far it sounds pretty good Dennis...good job and thanks for the info too. If you want to see something kind of interesting go to google search and type in "peal and seal insulation" (without the quotes of course) and check out some of the hits you get. Also try jiffy seal and/or other combinations with "audio" or "sound" it's interesting. This same conversation in this thread has been in other threads on http://forums.caraudio.com/vb/index.php and other places. Go on Car audio.com and do a search on "Tar" also do the "peel and seal" search...very interesting.

Some like it... some don't but people are using it...ALOT!. Also people complain about the tar or asphalt smell of Fatmat as well as many other popular sound deadening materials which tells me they are most probably almost all asphalt based and therefore probably pretty close to the same in sound deadening based on the thickness/density. Check this thread out too:

By the way here are some product web sites as well:

**Tom Welch** · 03-07-2005

The Home Depot stuff is called "Space Age Water Heater Jacket" it is claimed to be the equivalent of r-19 insulation. It is manufactured by Quality Heat Shield Sound Deadener. No joke thats the name on the label. They are located in Riverside CA. I have been unsuccesful in contacting them sofar. I'll post any results here as soon as I have some.

**69Rathead** · 03-12-2005

Have not found any of these previously talked about items at either Lowes or Home depot in my area. The closest I found was Peal and Stick by Dow Corning which was just Tar or Asphalt type tape 6" wide by 30" bout an 1/8" thick or so and it had no Aluminum on one side like the others. Just a wax paper type lining on both sides and it stinks of tar badly...not going into my car! Think I'll just break down and go on Ebay and buy one of the 100 sq. ft. deals there.

**Todds69** · 03-13-2005

69Rathead....The reason you may not find it in AZ is because the peal 'n seal is usually used for ice damning issues. They should be able to order you some.

**Todds69** · 03-13-2005

Here we go 69Rathead....Lowes has it under item #154017 and model #PS625 which ever they need for you to order. Called Peel & Seal 6"x25' for $12.47...Good Luck

**68BNUT** · 03-13-2005
