Spray-on Sound Deadening

Good addition to interior sound deadening. Installed an AWE exhaust on the OB Wilderness. It's a bit louder than I want to hear inside so trying to mitigate the noise. Bought two cans and it covers two coats in rte exhaust pockets including pulling the heat shield and two light coats on those. Doesn't over that much as everyone else noted. It did help reduce a bit more noise but not as much as the interior deadening of course. Planning to get another couple cans, pull the wheel well liners and do those too. Looks very nice. Just took another look after a few weeks of use and heavy rain - looks perfect.

This stuff is amazing. A little messy… But if you know what you’re in for it works wonders. My whole chassis was vibrating from a subwoofer upgrade to my rear quarter panel. Used this to coat the inside of the subwoofer cavity and it did exactly as it should. Nice and quiet. Will be using this again.

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.

Purchased an undermount sink for a vanity. Reviews on sound dampening pads were pretty sad and spray from the manufacturers is typically very thin. As they say, "Hold my beer and watch this." I'd suggest the best application would be inside a cabinet, so the entire bowl can be sprayed and not show, but mine will be exposed under a live edge wood top and steel legs. I applied two coats: The back half is sprayed and about 3" around the drain where the water will make contact from the faucet. It sounds like a very expensive, heavier gauge, now, without the hefty price. If you do this as well, just be sure to use gloves (it will stain and it's awful to remove once dry) and mask off around the drain and lip where the sink will touch the countertop to ensure perfect adhesion with your silicone, undermount clips, epoxy, etc. TAKE THE TAPE OFF WITHIN 5 MINUTES OF SPRAYING! If you dont, your tape will remain there...permanently. Since this product has great temperature tolerance and is under the sink, not in contact with water, it should be a great option for DIY-ers! I'm really happy I tried this!

It did work well, but it stinks (you'll need to air it out for a few weeks, and there isn't much in the can. I maybe did a 5x5 ft area w/ one can.

I couldn’t use for my project… but great product and trustworthy seller.

I sprayed the firewall of my SXS to reduce engine noise This product was extremely easy to work with. There was a really quick dry time for the thickness i wanted to achieve. I could reassemble the machine the same day.

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

Graet Product Ever!!!!.....

This product was easy to use when spraying into hard to reach areas in the trunk and door panels of my Mustang. One can goes a long way! My results are pleasing.

Two cans per door,double coat works for me.Asphalt in a can.👍

Very good product. When received the can is heavier than expected and sprays very thick but does an excellent job of reducing noise from the trunk, I would recommend this product for a cheaper alternative to the roll on mats. Two coats in the trunk and the two front doors took the whole can, but would buy again.

Stuff sprays nice and goea a long way
