FatMat Self-Adhesive Rattletrap Sound Deadener Pack with Install Kit - 175 Sq Ft x 80 mil Thick

This might be the worst product on earth. I installed this in my 1985 VW Vanagon full camper in hopes it would help with the noise. I put it on every flat piece of metal on the entire car. I removed all my interior, including all cabinets, panels, and insulation to apply it. It worked great for a few months until the smell started to catch my attention. I discovered that all the sound deadener had started to melt into a black goo. currently, I am in the process of removing this horrid product from every part of my van, including my new interior that now has tar all over it.I cannot believe the mess this stuff has made. i estimate it will take me at least a month and alot of $$$ to remove this smelly, disgusting, horribe stuff from my car.Please do not make the same mistake I did, DO NOT BUY THIS!!!!!

Could hardly believe it even though I had just installed it myself. Listen to the sound on my video. My own brother even said he thought I must have been banging the panel harder on the untreated area, but it was the same. Effective.

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.

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.

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. :)

Deadener starter to come loose from the panels during the summer. Worked great while it was attached. But once it got hot almost all the panels came loose. Even after cleaning with alcohol before applying.

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.

Very Happy with it but not cheap

Item received in good condition.Good product

It’s asphalt based. Would give off bad Tar smell come summer heat
