Haven't driven yet,I'm certain it will work out great ### ⭐⭐⭐⭐⭐ Great product and trustworthy seller. *by D***M on February 24, 2026* I couldn’t use for my project… but great product and trustworthy seller. ### ⭐⭐⭐⭐ 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. ## Frequently Bought Together - 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 - LUMITECO Bearings Equipped Automotive Car Audio Sound Deadening Application Wheel Roller, Heat Abatement Mat Wallpaper Application PU Smoothing Tool Seam Roller - Siless 80 mil (2mm) 36 sqft (3.4 sqm) Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (36 sqft) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/3557266-spray-on-sound-deadening](https://www.desertcart.com.pa/products/3557266-spray-on-sound-deadening) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-05-17*
