It sticks well but it seems to become a lot more soft and tacky in the heat compared to other brands! Great value if you're on a budget! It does have an odor kind of like a kind of asphalt tar smell but it goes away after a couple days. Decent quality for the price and the thickness is as advertised. Sticks on easy so installation is a breeze and it's easy to cut which is great! Review: Must for subwoofers. True 2mm spec. High quality. - Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more. ## Features - β˜… Siless VIBRO 80 mil is ultimate quality sound deadening insulation.

Easily moldable, cuttable with good scissors or razor knife, very sticky, works great. This pack was enough to do all 4 doors on a crew max truck, and I went wild on the fronts. I used 9 peices on each rear door which was just enough, and the rest on the fronts. I doubled up layers and even used some on the back of the door panels. If you follow the instructions and dont go wild you might even have extra left over. It works just like you would imagine. Without doing the entire cab there will still be road noise but this helped noise, better audio, no buzzing door panels, terrific improvement. It is kind of heavy, so extra weight is added to truck, but that really isnt a bad thing. It is noticable but in a good way. Get it. Use it. ## Frequently Bought Together - Siless 80 mil (2mm) 18 sqft (1.7 sqm) Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (18 sqft) - LUMITECO Bearings Equipped Automotive Car Audio Sound Deadening Application Wheel Roller, Heat Abatement Mat Wallpaper Application PU Smoothing Tool Seam Roller - LUMITECO Car Audio Sound Deadening Roller Seam Roller, 3-Pack Heat Abatement Mat Noise Roller Sound Insulation Tool for Auto, Sound Deadener Application Installation Metal Hand Deading Wheel Roller --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/503579249-80-mil-18-sqft-car-sound-deadening-mat-butyl-automotive](https://www.desertcart.us/products/503579249-80-mil-18-sqft-car-sound-deadening-mat-butyl-automotive) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-03*
