Bests & Worsts Reviews from Amazon

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.
