After reading too many forums and reviews I settled on this over Dynamat and eDead and a few others, based on the positive reviews and cost per sq. foot. This stuff installed great without adhesion problems, and the roller and knife from the kit worked surprisingly well.

Other guides and how-tos are absolutely right in regards to application of this kinda stuff: warmer = better. I installed this in my 1973 Mustang in the middle of my driveway in early December in Maine. Used a portable ceramic heater to warm up the interior of the car, and held the pieces once cut right in front of the heat element for a little bit until it was nice and malleable. It adhered much better and was easier to roll firmly into place.

Installed two layers in prime areas like foot wells in front of the firewall. I could feel and hear a notable difference once the inside was done: warmer, quieter, and reduced a lot of that metal 'ping' noise. Now its more of a dull 'thud', which should translate to much less road noise and rattle.

Good stuff!

The more I use this product the more I like it. I have developed some opinions surrounding this product & topic and here they are, again only my opinion based on my research and limited experience.

1. The FatMat is slightly more difficult to install (correctly) than the Dynamat Extreme. (the only other similar product I've used)

2. This FatMat product is 80mil and $2.20 a sq ft, Dynamat E is .67mil and costs $4.16 a sq ft (on date of review)

3. FatMat will conform and stick to about any shape but it may take more elbow grease and possibly heat. In some areas I did use a hair dryer.

4. If you take your time installing and use both ends of your roller, (the wooden handle end is very useful in the tight recessed and indented areas) you will get excellent results.

5. Surface contact is key and surface contact is key, did I mention the importance of surface contact?

6. The foil seems thicker on the FM. Just going by feel here, not very scientific.

7. Based on the product weight (not shipping weight) currently listed on Amazon, the FatMat weighs in at .46# per sq ft vs the Dynamat E at .36# per sq ft. This could be good or bad depending on your view.

8. Personally i think the extra mass of the FatMat is a bonus. Another product used for sound deadening is actually called Mass Loaded Vinyl or MLV. Its probably right above your feet on your vehicles firewall already. I know the theory is for the dampener (fatmat) to reduce vibration and the MLV with a decoupler (commonly foam) to stop airborne sound. Ive also heard people say you dont need much coverage with the dampener and while that may be truth for stopping vibrations when installed with 100% coverage I think it does more than that. Personally I went with about 75% coverage on the inside of the doors (outer skin) and 100% coverage just under the door panel. I then spray glued felt on the backside of my thin door panels before reattaching them. On the entire floor and wheel wells I went one layer 100% coverage followed by continuous layer of luxury liner pro befor carpet. In the rear cargo area I also added 1/8" thick MLV on top of the factory carpet pad but under the carpet.

9. Lastly I need to mention I was impressed by FatMats customer service. After ordering I emailed to see if there was anyway I could ensure shipment earlier. I received a response very quickly letting me know they would ship immediately and I would have it when i needed it. Very responsive. I emailed back thanking them and they emailed me back with a "you're welcome". Its the small things.

This product went down easily. I installed it when it was 70 degrees outside and it was very sticky.(This was a good thing) It easily contoured to all the bends in the places it was installed. The roller is more than adequate to ensure the mat is in full contact. I installed this in my 2011 Ford Ranger extended cab and it made a significant difference. I could have used another 10 square feet to finish the rear passenger door. I highly recommend this product. It's easy to install and works great.

I have never used any of these sound deadening products before, so I really can't recommend this over another manufacturers. however after three days of tearing out my interior, installing this and putting it all back in. I can say the car is quieter and has fewer clunks and rattles than it did before. However, while it is easy to use, the effort in getting to the sheetmetal is larger than you might imagine and you'll mess up some panel or plastic bit in the process.

Used on maxima. 4 doors, rear shelf, wheel wells & floors. My CDT comp in front & coaxials in rear sound greatly improved. Easy to use and very pliable. Good razor knife (provided with kit)
is all you need. A lot cheaper than Dynamat and works equally as well. I have used both and am a die-hard Fatmat fan. Get some and try.

Don't really see how anything could be much better. It's thick, super sticky, and and is easily cut with a straight edge and the supplied razor. Does smell like tar for a minute, but dissipates quickly. Hence the 4 stars. Will use again.

Don't waste your time buying the "Monster Cable" of the sound deadener industry called "Dynomat". This mat is thick and has great adhesion. It lays in without much effort and makes the difference in my 1968 Camaro SS.

I've been using Dynamat for decades, until I found FatMat. The 80 mil material is identical to Dynamat with one important difference...it's HALF OF THE COST!!
This stuff works great for dampening road noise and heat/cold from coming in or going out. This material is semi-easy to form to shapes, without the need of a heat gun. The adhesive backing is actually a little stickier than Dynamat, too.

As long as this stuff stays on the market, Dynamat has lost a customer!
