Design Engineering DEI Boom Mat Damping Spray | Spray-On Sound Deadener for Cars | Eliminate Road Noise | Dampen Vibrations | Enhance Car Audio | Covers 20 Sq Ft

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 1989 Toyota MR2. This vehicle happens to have the engine, and transmission in the middle of the car for weight distribution purposes. They car idles at 2000 RPM when cold, which produces a tremendous amount of noise and vibrations. Also on the road, especially the open highway, they car SCREAMS doing 65 mph at 4000 RPM. Something had to be done. BOOM MAT. I lined roughly 40% of the engine lid surface area with boom mat, and the results are awesome. I had plenty of boom mat left, so I applied it to various parts of the engine bay's panels. Perfect. Now the car is quiet and smooth. I can now hear the air coming out of my vents, and other little things inside the car that I could never hear before. I highly recommend this product for sound and vibration dampening purposes. All you have to do is wipe the surface down, to remove all the dirt, and dust. If there are any sensitive areas (nuts/bolts/VIN info) just go ahead and throw painters tape over it. From about five inches out, go ahead and coat the surface liberally. If it's a hard to reach surface, carefully use the straw attachment. Let it dry for the prescribed amount of time. This is literally a super thick, sound/vibration substance. If there is any unwanted boom mat overspray, I recommend carefully using some brake cleaner on a soft cloth, and gently rub it off(before it dries). It's meant to last, but you don't want to damage any paint in the removal process. BOOM MAT in a can is truly the best of Amazon!

I bought this to sound proof my Fox Box as it has fiberglass tubs. I'd estimate each tub to be approx. 2-2.5 SF inside as well as outside. I was only able to spray the insides of both before running out of spray. Way short of the 20 SF the can says it covers. Considering Amazon only has this on 2 day delivery, my project is cut short and I have to wait 2 days to finish. The stuff is great and easy to spray BUT ORDER AN EXTRA CAN! 1 can only covers 1/2 of what they say.....maybe less. Good stuff though! 4 stars due to lack of coverage.

Can runs out fast get more than one if needed i used under my car to help it from ever rusting out and some sound dampering it helped

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

I was expecting a spray with a bit of body. Didn't get it. Whether spraying up close or way back I just got thick paint; nothing at all like the (fake?) picture they posted up top here. I guess a thick layer of a tarry deadening substance is really beyond the scope of a common (expensive) spray can.Won't make that mistake again. When you're slamming a couple of tons of sheet metal down the road, this sort of deadening spray ain't gonna do diddly squat about all those sheet surfaces drumming and resonating and passing noise into the cabin. The scale of work for this stuff is more in line with sink undercoating. Not vehicles.Maybe I need to buy a LOT of expensive cans?

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!
