Comes with a razor and a roller

Cuts and installs easy so long as you are patient on bumps, corners and contours. The adhesive is pretty bonkers and if you have to pull it up to make adjustments it will leave marks behind. The adhesive layer has a bit of a tar smell to it but I only noticed it during install and it doesn't seem to have stuck around. I installed this on the walls, floor and ceiling of a cargo van to reduce the hallow cave effect and cut down on some of the noise from the outside making the body into a giant drum. End result was good with a significant reduction in reverberation inside the cabin. Comes with a razor and a roller for cutting and installation.

This is great stuff I was a little worried at first about ...

This is great stuff I was a little worried at first about the horror stories of it melting all over the car, I live in Fl. and cut a small piece and set it to a piece of plastic and left it out in direct sun for a week w/no problems. I covered all I could get to in the trunk not butting it to each other but more covering large areas of flat metal didn't do deck lid (but may when I see how much left over I have) and did the same to the back seat seat floor and quarter panels I had to use the car the other night and w/no side trim or back seats it was noticeably quieter the only thing between the back of the trunk and the back of the front seats was the vertically mounted electronics panel. Fat Mat is very easy to work with and "0" waste, it stuck quickly, cut w/large scissors. Anyone who says they have a problem w/this stuff probably works for the competition. Did the trunk and left and right quarter and rear floor pan w/50 sq. ft.in my 96 Eldorado and ordered another 50sq. ft.

Great for sound deadeding.

This stuff worked great. I had no trouble installing this on all the interior surfaces except the roof when I was restoring my vintage Karmann Ghia. It is better than the tar paper they used to use and I had no problem getting it to mold to the shape of the surfaces. I didn't notice any odor when installing it or when I finally drove it but it did take me another 6 months to finish putting all the pieces of the car back together after this was installed. I can't say how much quieter the car is because the car wasn't running when I bought it but I did install a quality sound system with a powered sub woofer and even though the music can be loud inside the car you can barely hear it outside if the windows are up. I did also add a layer of EZ Cool insulation on top of this and on the roof to block the heat transfer because this only blocks sound not heat.

Worked on an E350 diesel van

It's surprising how well this stuff works. I used it to (help) quiet a Ford E350 diesel van, sort of a sisyphean task, and much to my surprise this did a really amazing job. I was able to get the van from 84Db down to 78Db by covering the entire floor with this. They say 20% coverage is sufficient but that just isn't the case if you're really trying to get something to be quiet. More is better here.

I like this product better that dynamat

I did my entire 2006 Silverado 2500HD crew cab with this roll. I will need another roll to finish the doors and roof. This is my second vehicle to sound deaden with the first I used to dynamat. I like this product better that dynamat. It took me about 12 hours to do just the cab. The interior on my vehicle is pretty easy to take out so if you had a car with a lot of paneling ect it can be a pain. I have not installed my audio but the volume and clarity has significantly increased even without having done the doors. I found the dynamat to be stickier and harder to work with. It also came in sheets where this comes in a roll. This allows you to use a continuous roll across the entire cab giving it a much cleaner look compared to dynamat. Last time I sound deadened I got new carpet from stock interiors dot com and got the plush carpet option plus mass backing for added $40 and that mass backing also helped as an added layer. I plan on doing the same for this truck.

Love this stuff! Good Quality. Good Price.

Used this in a 95 Chevy C1500 Ext Cab. Covered the floors front to back, across the back of the cab, inside the rear quarters, and across the rear part of the roof. I had maybe 3 square inches of various scraps left over. The stuff is thick, dense, adheres well, and comes with a roller and cutting blade. The roller came off early in the process, so I took a cotter pin that fit the groove on the roller, spread it open around it, and then pinched it back closed, and continued on; still working after the job is done. I have an aftermarket exhaust on my truck with duals that have quite a rumble. I started the truck, with the doors closed, while the floor was bare and took note of the sound levels. After the install I repeated the process. There was a significant drop in the noise levels from the exhaust and no metal rattle from the stereo. Frankly, I'll probably pull the door panels and cover the insides of door shell and the rest of the roof before too long. The less road noise you have, the better your stereo will sound. :)

My experience, my opinion

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.

Just awesome!

I ordered this for my 2001 Civic coupe. I plan on driving this car for another couple years and that means the road noise needs to be reduced if I want to stay sane. lol As you may know, Civics are economy cars and so sound proofing the car is the last thing on Honda's mind when they designed this car back in 2000. This car picks up a lot of noise on the highway. Loud enough to get in the way of your conversations with your passengers. I figured, why not had some kind of dampening material to help with that. I did some research, came across this specific product, and attacked my two doors first. That alone drastically cut down the noise. About two weeks later, I wanted to do my rear deck but ended up doing my rear quarter panels instead. After doing basically the interior of the car, I have to say I'm impressed. I mean my car didn't transform into a high end Lexus or anything but my car did become a lot more quiet. It makes the car feel better and safer to drive. I can barely hear cars passing by on the freeway. Conversations can be carried with ease. It's great. Just some tips and suggestions for future buyers, if you're not running subs in the trunk, don't bother applying this in the trunk area. You won't notice anything. Attack the doors and the actual cabin first. Then, layer the Fatmat. Two layers of this stuff and all resonances will disappear. I wish I knew that before putting my door panels back on. Too lazy to fix. Oh by the way, I still have one sheet of Fatmat (about 5 sq ft.) left after doing the doors and quarter panel. This stuff can actually go pretty far. Unless you want to FatMat every square inch of your car, the 25 sq ft should be enough. I was worried I would run out too quick but nope!

What? I can't hear the haters on this with all the blockage.... WHAT?

So far so good. I installed this on my Superduty that has diesel exhaust rattle. I'm still working on installing on all the under carpet, but the rear seats seem to be better at this point. I also have to do the doors too. It takes time and be patient. Cut into smaller workable pieces and save yourself some of the headaches. I tried working a 66 x18" strip and I knew almost immediately that was the WRONG thing to do. I should have cut that into three separate pieces and worked one at a time. I eventually got it all tucked into the groves and such, but I had to use a heat gun to really warm and make it stretchy. Work in sections and not one big piece. My caution and it only exists in my head is the fear that the item will warm this summer and melt all over like ice cream or smell like a freshly tar coated road. Here's to my anxiety. :)
