They also sell a similar item; it's self-stick butyl-rubber flashing that's used to seal windows and doors. However, the Zilla-mat seems to be competitively priced.

 

ZIlla mat is the butyl rubber 50 mil, I am very happy with it but I know people who have used the Dynomat Extreme and it is what it says, Extremly insulating (Noticable over regular dynama) and its extremly expensive. Ryan

 

I checked out the dynamat store. $200. The Zilla will be about $100. I will compare the gutter repair material and report back for any others that may be following this thread. (I hope it doesn't put off any odors or fumes. Maybe that's why we haven't heard from Dewayne lately?) Thanks for the input everybody. :-) Jag

 

I'm doing the same thing I was planning on doing mine this coming weekend but may have to put it off. What type carpet are you using? I was going to lay down the sound deadening and get carpet from a shop and cut it myself and have them sew the edges if they would go for that.

 

I bought a roll off the Ebay. It's grey fine pile. There will be no edges showing as I am tucking it under the SS edge guardes. I am going to have the upholstery guy put some edging around the floor mats for me. Good luck, Jag

 

I bought Dynamat Extreme off Amazon, the best price I could find. It will dampen vibration and has a little bit of thermal insulation but not much. I sprayed two coats of Lizardskin on first, followed by the Dynamat. Lizardskin advertises a 40% reduction in heat transfer.

 

I have been running this stuff for about 4 years and 80k miles. No problem so far.

 

I'm a liitle slow to respond these days. It's called Peel and Seal. Lowes sells it in 6" x 25 foot rolls if memory serves. It's a roofing and gutter product. It's about a buck a square foot. After installing it in four or five vehicles I can say with some confidence it is quite sufficient for about 90% of your vehicles. I wouldn't use it on a transmission tunnel if I lived in AZ. I know it will stay put on a door panel in 95 degree temps for many years. My truck is very quiet and has a performance audio system with small subwoofers. Dynamat is wonderful stuff, and something similar is required if you have a 1000W audio system. Other than that, it is extreme overkill for most of you. The Zilla sounds similar to stuff I buy from Elemental Designs audio called eDead. I'll have to check their prices on the good stuff. Bottomline, anything that is dense like tar or butyl rubber will be more than sufficient to absord vibration and noise from any Effie that doesn't have a stupid loud stereo with bass. Save your money for something more important. You can come back here and eYell at me if I'm wrong.

 

The same material as the peel and seal is sold in wider rolls as ice dam preventer in colder climes. If you live where ice dams are unlikely to form, your building supply depot should be able to order it for you.

 

The ice dam I used lacks the aluminum layer peel and seal has, but if would make a good first layer and it's cheap.

 

Dewayne and Ax,
Do these products stick well enough to use under the head liner on the roof as well as the verticle surfaces?

 

Have I used it on roofs? I have, but I would probably recommend using something rated for more heat. I have had zero failures with Peal and Seal, but I generally just use it on floorboards, doors, cab back walls etc. Whole trick to permanent install is to apply to a clean surface and warm up the Peal and Seal with a hairdryer or heat gun. I use a small roller, and use a screwdriver handle for the tight curves. It easily conforms to curves if it isn't cold. I've seen the expensive stuff fall off other peoples cars if the install was careless. Here is a link from Elemental Designs Audio.

It's butyl rubber. Note the thickness differences. Thats' most of the price difference. Rated for install at 50 degrees without warming it up. I;d warm it anyways if it's not hot out. I installed some last year on my wifes Escape. The price has come down. UPS shipping of course. I live 200 miles away so it's not expensive for me. If anyone orders , be sure you are buying butly rubber versions v45 and v120 are butyl. The v4 is closed cell foam and is for the back of plastic door panels. I also avoid the liquid. I have used it on plastic door panels as well. Not worth the hassle to me, when stick on works.

This is a link to Lowes Peal and Seal. It is a dense tar with an aluminum backing. Really no cheaper, but no shipping charges for most people. Perhaps Home Depot has it too?

 

All good information. I'll have to remember this link for next time though. I got lucky last week and won a big box of the Dynamat at the Sacramento Vintage Ford monthly car show. It had 36 square feet total which is more than I needed. The install is done and the noise is way down. Thanks for help everyone. Jag

 

I just did my whole cab floor and door panels with SecondSkin Audio brand. I won 2 boxes totaling 40sg ft from a local show over the summer. They had a silent auction and won that for $25 and then won a $100 gift certificate to DTS for $10.

I regret it now but I gave the certificate to my buddy so he could use it on his project

 

I use the stuff that looks like HD bubble wrap with aluminized mylar on both sides from my local Home Depot on roof. Attach it with 3M spray upholstery glue sprayed on both the sheet metal and insulation.
