Reduce sound vibrations in your car! Works great! This is not sound proofing, it is Sound Deadening
Size: 10 sqft, Size: 10 sqft
This Butyl rubber sound proofing kit includes nine 15 1/2" x 10" peel and stick panels. It really is a lot of coverage, but I still will need a second box to finish my car doors. The instructions are easy to follow and the only tools you need are scissors or a knife and a small roller, but you could get away with using a pan scraper to press the product down. You may need paper and a pen to make a template for certain areas, though. I used some cardboard from my recycle bin to cut template pieces for the hard to see areas inside my doors. This is fairly easy to install once you have it cut into pieces, just peel the backing off and stick it on. Be very careful to not let it stick to itself, as it will be nearly impossible to separate. This stuff is crazy sticky! No worries about it coming off once you've stuck it to your car.
To add this to your car doors, you will have to remove the interior door panels, but there are lots of YouTube videos on how to do this on all sorts of cars.
Note that is is sound deadening material - Not sound proofing! You do not need to cover 100% of the car with this. The material is designed to stop noise from resonating through metals, so even one piece of this on a large area of sheet metal will stop the sound vibrations quite a bit. I am covering about 80% of my car doors with it, then planning to put sound proofing on top of it. This sound deadening material needs to come in contact with the metal surfaces to stop the sound vibrations, so it would not be very helpful to put it on top of sound proofing material.
Also note that the installation requires temperatures above 50° Fahrenheit. Since it is winter, I've warmed up my garage while working on this project. In low temps, the sticky stuff would probably have trouble adhering to cold metals. So far I have tested just having it on my front doors, but I already can hear the difference. This soundproofing definitely does minimize road noise and external sounds from getting inside your car. It also stops music vibrations, so my radio now sounds clearer than it did before. I don't plan to pull out my vehicle carpet to install on the floor, but I would imagine that if I did it would greatly reduce the road noise even more.
Definitely five stars on this product!

Quality mats that provide noticeable noise suppression
Size: 10 sqft
I used these mats when I replaced the carpet in my Chevy Tahoe. Cutting the mats to size was easy enough with a utility knife and a straightedge. The adhesive backing stuck fairly well, but I used a roller to press the mats into place on the metal panels, which seemed to help them adhere a little better. Under the old carpet was the type of insulation you'd typically see under carpet in a typical home. It was worn, so I tossed it and installed the new carpet directly over these new mats. The before & after difference in noise was minimal, but noticable. But I only installed them on the floor - not in the doors, rear hatch area, firewall, or roof. So overalll, I'm pleased with these mats as they provided the noise suppression that I had expected.

Easy to cut and easy to install
Size: 10 sqft, Size: 10 sqft
You receive 9 sheets of RUNSUNSPRII Car Sound Deadening Mat that each measure 9.75" x 15.75". This calculates to a total of 9.6 square feet in total for all of the sheets. Of all the different styles of sound deadening mats, foil lined butyl is the best type for eliminating vibration. This quality product has a printed gridwork of 2-inch squares on the liner to aid in cutting the correct sized pieces.
Even with as sticky as this product is, it is super easy to cut to shape with one pass of a razor blade. OEM auto manufacturers use this same kind of product extensively on the inner structure for sound deadening and to block sound and air transmission through all sizes of holes and cutouts. Because it is highly waterproof, it also is perfect for blocking areas to prevent water intrusion. The very sticky pads adhere to all surfaces and are very flexible and will conform to fit many areas. Because it is thin, it is ideal to install under interior trim panels without causing interference with how the panels fit.

Solid quality and good price
Size: 10 sqft
I bought this for my custom built camper van and it’s been great so far. For $24, the amount of coverage you get is totally fair, and I’ll probably grab a second box to finish everything. It’s easy to install with just scissors and something to press it down, and making quick cardboard templates really helps for tight spots. The adhesive is insanely strong, so once it sticks, it’s not going anywhere (just don’t let it stick to itself). Keep in mind this is sound deadening, not full soundproofing, but even with partial coverage I can already hear a difference in reduced road noise and vibrations. I’m using this as a base layer and plan to add soundproofing on top, and so far I’m really happy with how it’s turning out.
