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. :)

This stuff is exceptional! It's priced much more competitive than other sound damperes and applies easily. I have an 08 Honda Civic and if you know anything about these vehicles you know that road noise is an issue. I have applies this product to all four doors, & the trunk roof and floor (including over the wheel whells). The road noise is now much more tollerable. Also I have a complete Focal speaker system with a 10" boxed sub and a Alpine PDX-5 amplifier. The system sounds exceptional and has solid base that has greatly improved by the sound deadening material. I can crank the system up pretty nicely, step outside the vehicle and not hear much sound from the audio system. If you really want to improve your interior sound this is the way to you but if your simply looking to disturb your neighbors and everyone else around you then move along. I figure my next step will be to purchase another order of this excellent product and apply it to the floor of the car.

Never installed this stuff so I was skeptical. I read that this specific type and brand was just as good as the name brand stuff but a much better price. I bought a 50sq ft roll of the 80mil. It did the whole interior of my 66 chevelle's floor. From fire wall to the trunk. Even enough to do the doors. I bought another roll to do the trunk and roof. I think I will double down on the fire wall and floor to make sure it's good to go. I bought it more for a quite ride inside then for any stereo ststem issues. I think this stuff will work great. It's easy to install. I will say this, the roller they send with the kit broke in the first 5 mins. I bought A good one from a local auto parts store for about seven bucks so I wasn't out that much secondly it was about 50° in my garage when I did this it was still pretty pliable however I use my heat gun anyways to make sure I got a good seal I can say after being heated up maybe too much you did get a little bit of odor of tar I read for some guys The odor was an issue once the car was in heat for sometime All in all I think it's a good deal and worth a shot

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.

BRIEF: This cheap stuff definitely can make your car quieter... but not by much. for some frequencies of road noise, it will decrease the noise by as much as 2-3 decibels (going by instinct, not audiometer). on other road surfaces, this will do very little. but, i'm happy with this product, and plan to buy more. SEMI-BORING DETAILS: i know very little about cars. i know even less about craftsmanship. i don't even know if i could put 2 nails in a wall so i could hang up a painting straight. i have a very mild case of hyperacusis. in english, it just means that i am DARN sensitive to noise. even causes pain, discomfort. i hope no one laughs at me. but if someone else does, go ahead. years ago, my previous car was a 2006 subaru wrx turbo with loud sports tires. this was one of the loudest and least sound insulated production cars on the planet. i think this car and it's daily noise attack was what cause my sensitivity to sound. after 130,000 miles, and very worn and loud tires, i had to change out of it. but before i did, i bought the fatmat. and, as fate would have it, my 9.5 year old car with 130k miles started having expensive problems. had to disconnect from the wrx soon. only 2 months ago, i got a 2012 mazda 6 - which is an awesome car by the way. so, i had spent about $60 on fatmat for my old car, then had to get rid of my old car before i could put the fatmat in.... now i have a "newer" car, that i was afraid to touch and alter its "virginity" or "newer" car status. .... couldn't take the road noise anymore. so, with fat mat just sitting in my house for months (!), i decided one day to put it in soon. i called a bunch of people like mechanics and dealers and sound shops for estimates of how much $ to put this stuff in. was told: "just the trunk? $100", "whole car? hundreds" ok, so i'm too lazy or scared (didn't want to mess up this gluey sticky stuff) to put it in myself. but i didn't want to give someone $100 to cut sheets of "rubber" and just press it into my car. so, i decided to do it myself. was a little concerned: would it bend? would it stretch and mold to my car? can i take off the doors? so, i decided since i was lazy, and this was the first time i was ever going to do this, i thought (and read the internet) about what's the easiest place for a rookie to try? the trunk (no need to take panels off). sure, putting this stuff in the doors can block out a lot of wind noise. putting it in the headliner does a lot too. but to take off the door panels takes time, mild technical knowledge, labor. and, ok, a rookie takes off the door panel and maybe even the headliner..... can he put them back?! WHAT I USED: flathead screwdrivers, sharp and big utility knife. no ruler or measuring tape because i'm lazy... WHAT I DID: so, one summer day, after deciding that i'm not paying someone to put this stuff in, and going based on what i saw on internet videos, i drove to an empty parking lot far from anyone or traffic. opened the fatmat box FIRST (open fm first and let it sit in sun while you get everyting else ready). there are big sheets rolled into a multilayered rectangular prism (seemingly fitting a rectangular shipping box) with a small knife and easily breakable small rolling pin. also super simple instructions. i pulled everything out of my trunk: trunk mat, tools, spare tire. i just left it on the ground away from me and the fm that was near me. in the trunk, i just saw bare, flat metal. and a big "hole" in the center with a cylinder sticking up.... where a spare tire goes. people say vacuum, primer. yea, they're right - that would have done a better job.... but i'm lazy. i just wiped the metal off with my hand and picked up big pieces of dust up threw it away. ok, so the fat mat is sitting in the sun for maybe 20-30 minutes on a hot summer day. indeed, like other people say, this helps. the mat will get more malleable, stickier, slightly easier to handle if you don't get your whole hand on the sticky side.... just use your fingertips if possible. so, i just minimally unroll the rectangulr prism a foot, then cut off a big piece where there is a mild bend [remember when you get this stuff, it will have been in a rectangular box for a while]. i just cut where there were creases/bends/sides were that conformed to edges of the shipping box. then, i took off all the paper backing of that 3' by 1' piece i not professionally (but not raggedly) cut off. take it to my car, look for some wide place i can put it down... then put it down straight horizontal or vertical. i also put a lot where the spare tire would be. once the fm was partially on, i used a knife to slice the fm wherever it wasn't bending well. then i just pressed it down. was surprised i was able to get it on so well and that it stretched like the pedals of a flower. i pressed in with fingers. then, i took the cheap rolling pin provided. this plastic handle, metal shank, plastic roller broke in less than a minute. i was indeed pressing hard, but the plastic stretched under the weight and force i was applying. rolling thing broke off from metal handle. tried to reattach the cylinder to the handle, tried to angle it when i rolled so it woul stay on.... this broken rolling pin turned out to be unhelpful at first. too lazy to go buy a new (better) one at home depot, i looked around, saw i had two screwdrivers. i used the flat end of the screwdriver to start pressing the fatmat (fm) in. i even used the sharp right angle of the screwdrivers to really "slash" and "press" this stuff into my trunk. i knew since i had a metal surface under the fm, i couldn't do any damage. i even lightly stabbed the fm into the trunk. my fmatted trunk may not look pretty, but i got it in and on tight.... i did use the rolling pin a little... but it would always separate on me every 14 seconds. super annoying. so, i repeated this process again and again for 2 hours. unroll fm rectangular prism until i reach a 90 degree bend, use my own big utility knife to easily cut..... look for a good place to put it, press in with flat side of screwdriver. ONE MISTAKE i did make was putting in one piece, then pressing in so aggressively. after 30 minutes, i figured out it would have been faster and possibly more effective to put down lots of sheets. then, once i have one layer, i jumped into my trunk (my weight is definitely going to press fm in deeper), the press and slash, roll and finger push that fm everywhere. i could also sit in my trunk, turn every which way, press slash, etc. COVERAGE: so, 25sq feet is enough to put almost 3 layers into the trunk of a midsized sedan (2012 mazda 6). REGRET: i regret i didn't use a heat gun.... (now how many of us have heat guns???). i should have just used a blow dryer on max heat. it would have molded this stuff in better. but again, i did it in the summer, left the fm out for a while... hoping the hot nyc sun will make my trunk so hot that eventually this stuff will meld and mold to achieve awesome adhesion. RESULTS: i tapped on the trunk when i was done. definitely more "solid". like there is more metal there to block out some of the noise from the rear tires. SUMMARY: i'm glad i did it. car is quieter, more comfortable to drive and sit in. this stuff is cheap. if an amateur like me can put it in, anyone can put it in. ADVICE (for trunk): just leave this stuff out in the sun for a little while... do it on a hot day (no joke), maybe buy a metal roller (not the plastic one included with this kit). cut, put it on, do one layer first, hair dryer (to make fm even more stretchable and more easily moldable.... then get in your trunk, sit on your rear end or balls of your sneakers, press/slash/stab/roll, turn on your feet while sitting inside... repeat repeat repeat. if you get air bubbles, slice it open with a knife, press in really really good. if you have stuff left over... for goodness' sake, don't waste the stuff you paid for. find someplace it will fit in and press it all in. this stuff is only a few fingernails thick. if you have some irregularities... like some pieces asymmetrically on top of each other.... who cares? just get as much fm into your car as u can. this stuff will do you no good if someone is in garbage. make sure it all ends up in your car. even under your spare tire if nowhere else. final words: ok, i know this review was long, maybe a little repetitive... maybe a little boring.... hopefully it helps one or two people out there. btw, if you really want a quiet ride, go for pirelli cinturato p7 all season plus tires. quietest tires man ever made. most annoying noise from the car that you always hear is tire/road contact noise when car is in motion. wind and engine noise can be mitigated just by slowing down or driving sanely..... but road noise will alway be with you even in local driving. if anyone has ? or feedback, please do reply. i shall attempt to offer helpfulful advice. thank you for reading
