Design Engineering 050220 Boom Mat Spray-on Sound Deadening to Reduce Unwanted Road Noise and Vibration 18 Ounce (3 Pack)

This product works great as an addition to other sound deadening products. I was installing Fatmat and used this product as a compliment to areas I couldn't otherwise cover. My 65 c10 is dramatically improved and very quiet.

Item met every expectation, thanks you

Not sure how much it deadens sound but it goes on nice and has a nice texture.

Ok so first off this works great, but put DEI's insulation down, with some of there boom mat with the adhesive backing, there under carpet padding and put this on top for a nice black finish, to really deaden the sound or just put this product down by it self and buy like 6 can's maybe 8 that's a real number, you don't necessarily need a lot for small areas but if you wanna cover big areas, like the floor pans or the back of the cab you need a lot, the thicker the better lol light coats work up to what you want, other then having to buy more it works I like it, I already made 2 other people buy this, you can't really loose it definitely does work with all there products together, really well actually, but if you just buy this it will work just don't expect a lot unless you buy a lot.

it does its job and thats what i needed

The media could not be loaded. I will admit, I did not use this for its intended purpose. It's definitely not meant to be sprayed onto thin sheet metal/ductwork to reduce noise/vibration. But it actually does pretty decent. In my video you can hear the difference between bear ductwork, boom mat, a thin layer of boom mat, and a thicker layer of boom mat. All of my paint was one coat.The reason I'm giving is such a bad review, is because the paint absolutely flies everywhere. While in one of my photos I did get a little overspray myself, all of the drips on the wall were purely from the paint itself. I did not spray there, it spat those out itself. Now granted I was looking up, and spraying at a 45° to 75° angle, But nevertheless it's still sprayed absolutely everywhere.

I used it to cover my trunk and the passenger side of my car. I just ordered another 3 can to complete the job.

Does not cover the square footage they say
