Works better than good
I was skeptical but this stuff is outstanding. Goes on beautifully and definitely blocks some good amount of noise out. However, buy double what you think. It sprays HEAVY and one can last maybe 30-45 seconds of spraying. I used 6 cans just to do the bottom of the cab on my f150

Very impressive product!
One of the coolest products Iâve used in a while! Iâm a big sound dampening nerd. Been one of my favorite modifications on my truck that Iâve been restoring. Older trucks have no coating on the undercarriage. This is the perfect product to stick under your truck. DEFINITELY A CONSIDERABLE UPGRADE. My only recommendation is insure you have a nice clean surface. It will not adhere to grease at all.

As advertised. Works to seal and dampen
Works as advertised. Please note even when dry, it is flammable, so if you want to use near open flame, that’s a NO. It is similar to a paint you might use as a truck liner spray. Black, tough, but it expands slightly as it dries. That gives the sound damping you are looking for.I wish the cans were twice as big. I’m glad I bought the three pack.

Sound deadner
It works well but definitely tape off and cover up anything you don’t want over spray on and beat rezalts is to spray almost 2 feet away from your project

Exceeded expectations
Used this in the doors, fenders, undercarriage to help quiet it down on the highway.It worked far better than expected, eliminating most road and tire noise with just 1 heavy coat.

Horrible paint, pretty decent at isolating vibration.
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.

Does the job
Great sound reduction for door panels on autos.

Great vibration absorption!
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.
