B-Quiet Extreme Sound Deadener 50 sqft. roll Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

This stuff does make a difference, but it will depend where you install it and what vehicle you're installing it in. If you're driving an older or cheaper vehicle or one with little sound insulation this will help you more than with expensive or newer vehicles. If your door panels and the floor of your car are just sheet metal, B-Quiet will deaden vibration of that metal as well as block a decent amount of road and engine/drivetrain noise from coming through those surfaces. It may also help a bit with insulating your car when using the heat or AC.I installed this in the doors and under the carpeting in a 2000 Honda S2000. One Saturday, I had time to do the passenger door and under the passenger carpet area. I didn't have time to do the driver side on that day, and driving it, I didn't notice much of a difference, because I was still dealing with the road and ambient noise coming from under my seat and through my door. A couple weeks later I installed the B-Quiet on the driver side, and was excited to take the car for a spin. Not thinking, I put the top down because it was a nice day. I didn't notice any difference because there was so much wind noise. So keep in mind, in a convertible, this won't really help you with the top down. I then put the top up, and drove around in neighborhoods and on the highway. I noticed on the highway that things were quieter, sounds were duller. When I drove over the normal cracks and bumps of the highway, the car felt less like a Honda and more like a BMW. I grinned a bit at how much this stuff had helped and really enjoyed the lack of constant white noise coming from the left, right, and underneath me. In neighborhoods, most of the noise in the car comes from the engine anyway. When you aren't traveling very fast, there isn't a ton of road noise. For this reason B-Quiet Extreme seems to mostly help on the highway. I'm interested to see if it makes things quieter when driving in the rain too.In the picture, see how it contours over the shapes inside the door. To block road noise, you want complete coverage, or as close as you can get. You can double layer it if you have extra, but do a single layer first on all your application surfaces to make sure you have enough before doing a double layer, and make sure to double up on areas that have more sound coming from them, which will depend on the vehicle. This stuff sticks really well, but if you accidentally touch it to the wrong area before it's quite where you want it, you can remove it without too much effort and place it where it needs to be. Once it's placed, contour it to the surfaces with your fingers, and use your hand to smooth it down to avoid bubbles. I cut pieces off the roll with a pair of scissors, which was not that hard.To install it under the carpet of the car, I removed the seats, the door sill plates, and a couple other connectors and panels, then lifted up the carpet. It's important to clean a surface before installing B-Quiet Extreme. I used paper towels with some rubbing alcohol on them. Mostly they just picked up dust, sand, and fragments of leaves, etc. Let it air dry which won't take long with alcohol, and install B-Quiet. Cut this stuff to the shapes that you need and don't leave open areas on your application surfaces if you can help it.

Applied this to the inside of my Porsche 944. Did the rear spare tire area, rear wheel hub area, floor boards, under the rear seats and inside the doors. Took me about a day and a half to apply but I took my time and cleaned and de-greased everything first. Product seems to be of good quality. Application was easy. I haven’t finished with other restoration projects so I can’t say for certain if there’s an improvement in the noise levels in the car but can only think it would be much better. I would recommend a roller to make the job go faster and easier on your hands.

I lined as much as possible in a F150. Inner doors too. Suggest the surface be as clean as possible. Glue is very sticky. One roll goes a long way. Highly recommend!

Used it to line the inner tailgate, rear side panels, wheel wells, and both front and rear doors. Material does not want to come off once it is applied. It made a big difference in the outside noise and vibration. (1997 Jeep Cherokee)

Item was received on time and has been installed with usual good results

Made my VW quiet. I used this and fat mat and Jute. I only rated it 4 stars because i wonder if you could get the same results from just Jute material? This is great for areas you need thin protection.

Works as advertised.

This stuff works great .... priced way better that that other Mfg that everyone uses.
