Overall, this worked well to lower the road noise in the cab of a 25 year old pickup. I used to have a problem hearing/talking on phone calls because of road noise at interstate speeds, but after installing this I'm able to hear and be heard on the phone.Benefits:- Easy to install- Super strong adhesive- Easy to cut to size- Small enough that all the dash components were still easy to reinstall- Reduced noise in the cabInstallation Tips:- Use scrap cardboard to mockup and test fit pieces- Use a box cutter or scissors to cut pieces to size- Use a box cutter to cut sections in the disposable adhesive backing. This will allow you to install it in sections, without having the entire adhesive side exposed and getting stuck where you don't want it.- After cutting sections in the adhesive backing, remove a small section in one of the corners and stick that to the vehicle. This will let you do two things, test fit the final piece, and hold it in place while you peel back the other sections of adhesive backing- Use a roller to seal the mat against the vehicle. This prevents moisture from being trapped between the mat and the vehicle, which could lead to corrosion.

If you purchasing Siless Liner 157 mil (4 mm) Sound Deadening mat, to block unwanted sounds in your car, this is what you need to buy. But wait! It's not the only thing you need to buy if you want to "actually" deaden sound.By itself, it will definitely block a noticeable amount of sound, and, most likely, that's all you realistically need. But... But... If you want the Siless Liner Sound Deadening Mat to really help you take it up a few notches, to get the best sound almost bordering on soundproofing, listen up.You will have to install traditional butyl rubber first. Doesn't have to be the Siless brand, but I'm sure they would love to sell both to you, I used both Killmat (80mil) and Noico (50mil).I have a Honda S2000. It's a two-seater convertible sports car if you don't know what this car is, and it's loud when I'm driving above 60mph. I also happen to have a sound system installed as well. Other than that, the car is stock. I first installed the butyl rubber on the car's interior sheet metal. I went all out and covered everything I could. I didn't need to but I wanted to. I was extremely impressed with the results. But I wanted to go further. Not because I needed to but because just wanted to see what it would be like.So I bought Siless Liner 157 mil (4 mm) 36sqft Sound Deadening mat to go on top of the butyl rubber mats. I put this over every area I installed the butyl rubber. I had to be careful of clearance issues since I added a significant amount of underlayment, and you should too.If you put butyl rubber sound-deadening materials in 50% of the total interior area, you'll hear a noticeable improvement. If you put butyl in about 80% of the total area, you'll be even more amazed at the improvement, compared to before.I originally did all the above myself, so that's my experience and so your mileage may vary.I then installed the Siless Liner Sound Deadening mat over every place I could even going further than I could with the butyl rubber. I used the Siles Liner in areas where butyl rubber would not have been effective, such as the roll bar hoop area and large empty cavities or holes.I covered everything I could, firewall, doors, floor pan, transmission tunnel, trunk, trunk lid, fuel tank area, rear quarter panels, and rear-wheel tunnels, in Siless Liner Sound Deadening Mat.WOW!! The Siless Liner Sound Deadening Mat was the icing on the cake! Let's not forget, this car is a convertible sports car so it will never be a quiet ride, ever. But I can now actually have a conversation with a passenger at a normal-ish volume! This also means I can now have a normal hands-free phone call without having to plug one ear to block out the noise! My sound system sounds so much better! Just by going through the install process, I looked for any vibration, rattle, squeak, and noise-prone areas to either eliminate or reduce unwanted noise production. If you forget this step, the inside and outside of your car will rattle and buzz. I skipped this step the first time around. But did it right before I installed more butyl rubber and the improvement was impressive, especially inside the car. Outside the car, I didn't notice a difference until I put the last layer of Siless Liner Sound Deadening Mat. The sound deadening mat works both ways from what I can tell. If I turned up my music, as loud as I occasionally do, parked in the attached garage to the house, with the garage door closed, I would be barely able to tell the car was playing music in the garage. It sounds like it is another car, just a little bit down the street, with a very loud base. If you stand 20 feet away outside the car, the sound system is noticeable, but not obnoxious by a long shot.Get a 3 piece wood/metal roller set as well, which makes quick work of large areas.

I have had this one my doors for about two years now and the glue is giving out already. So def a good material but needs better glue backing that last longer.

The adhesive on this product is nice and strong and even sticks to fingers but it's easy to remove from skin. It does a pretty good job

Very happy with this product. I covered the hood, entire floor and 4 doors on my diesel Exursion. I then put 36 sq ft of Siless liner on the front floor boards up to the firewall. I only had enough to do 1/3 of the floor. Need to order more. This has greatly reduced the road noise on my Excursion. The liner makes all the difference as the butyl deadner really didn’t cut down on the diesel engine. Product is very sticky! You aren’t gonna pull it up to move it. However it is much easier to install than butyl floor deadner.

Really easy to install, it did quite things down a little bit. If you want a substantial difference especially on rougher roads I heavily recommend going with the butyl style mats.
