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.

it does its job and thats what i needed

The media could not be loaded. I used this on my coupe and each can only gave me 2 solid passes for each fender liner. Works great with my loud tires and stopped a lot of vibrations coming through. Was very messy though. Id put something down like old cardboard on the floor to catch the drippings. WEAR A MASK TOO.

Not sure how well it actually works because my situation was unique. Easy use.

Item met every expectation, thanks you

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.

Great adhesion and it sprayed even and easy. If used for it's intended purpose it works great! I used it under the trim around my wheel wells and exhaust path. Tire road noise and exhaust noise are gone. I used it in conjunction with sound deadening mats and door seals. Great product at a great price.

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