Additionally, it can be top-coated with paint after just six hours of dry time, allowing for a seamless finish. Trusted by professionals and enthusiasts alike, DEI’s Boom Mat Deadening Spray not only improves sound quality but also helps maintain a serene cabin environment free from disruptive engine and road noise. Its easy application, quick drying, and strong adhesion make it suitable for both large and small areas. With excellent heat resistance and long-lasting durability, this spray ensures effective noise reduction and a more enjoyable ride for years to come.

Review: Great product - It is good quality it fits perfectly in thought spots it's so cheap I love it it doesn't look bad and it's functionality is great
Review: I Guess it Worked??? - Used this to spray the liner of my wheel wells. I had enough to do the two front liners. Will probably need 2 cans per liner. Not a night and day result but possibly a slight less road noise in the cabin. If anything I think it made it seem like the back was louder but maybe that’s cuz it actually worked. Didn’t use a decibel meter before and after so can’t say for sure it’s doing what it claims.

### ⭐⭐⭐⭐ it helps (a little)
*by N***Y on May 14, 2014*

I drive a turbocharged 2006 subaru wrx with 116k miles on it. this affordable sports car is one of the loudest cars in the world in part because subaru put almost no sound insulation in the car so it could be light and affordable. road noise has been so bad that it actually hurts my hearing now. ordered 4 cans of this stuff after reading a lot of other amazon reviews. I agree with many other reviewers: this stuff does help, but not that much. I had my mechanic take the wheels off, and spray a lot of this stuff onto the wheel wells. three cans (yes, three) was able to give me a decent coat on the four wheel wells. with the remaining can, I just had my mechanic spray under the driver seat - an undercoating. there definitely is a decrease in road/tire noise. i'll guess it's about 1 decibel. the other reviewers are right - you'll need lots of coats of this stuff if you want to make a big reduction in noise. [side note: for those of you who would super quiet cars, change the tires. sure, very expensive - but then you aim for the source of the problem] I did use 3m 03584 Professional Grade Rubberized Undercoating - 16 oz - before. In fact, I think I've used 10 cans total on all the wheel wells. I think this boom mat is a little more effective. my mechanic said it was thicker. boom mat also comes with a small, long, spray/straw like tube that can be attached to the can. in other words, boom mat can be sprayed through a provided tube that concentrates the spray that comes out, enabling you to reach into even deeper places for greater buildup. sure, it's slow... but it can enable those who wants to reach (almost) everywhere to do so. so, I like this stuff. my car is quieter. seems easy to use. darn cheap too. buy only 4 cans of this stuff, and get free shipping from amazon. comes out to only $10 a can. cost effective, helps (a little), and can always put on more later on for even more effect. I plan to buy more in the future.
