Did the floor pan, doors and back wall in the F150. It’s nice that it’s 50% thicker than the thin stuff along with the Aluminum coating for some heat dissipation . It was easier to install than just plain butyl rubber in the summer heat, the indents made it easy to see when it was properly set and rolled and easy to cut. Definitely recommend for the price point. Made a huge difference in exhaust noise and the sound system sounds much tighter as well as a result of less vibration and noise intrusion. I used this in combination with the Siless Hybrid to cover both vibration reduction and sound infiltration. ### ⭐⭐⭐⭐⭐ Get Rid of New Ranger Tinny Door Noise *by on Reviewed in the United States September 17, 2025* I imagine most of these things are fairly comparable, but I bought this one because it was what a guy used on YouTube for my exact problem on my exact rig. I bought a new Ford Ranger Lariat and I noticed that if I close the doors slightly hard or with the windows doors open, they sound like tinny trash. Not what you would expect from a $50k vehicle. Watched a YouTube video to get the confidence to start and finish the project and it was super easy. I didn't do as many layers or in as much detail that the guy did, but it solved my sound concern. Since there is enough left over after doing the doors, I may do the headliner at some point. One thing I got that I feel was worth was a roller to press on. It seems unnecessary, but it definitely helps adhere the panels better so they are more secure. So worth it to me for sure. ### ⭐⭐⭐⭐⭐ Yes *by on Reviewed in the United States May 11, 2026* Easy to work with, quiets doors very well, cuts very easily to any shape needed or wanted with scissors, sticks well, and molds in to place well ## Frequently Bought Together - Siless Max 120 mil (3mm) 30 sqft Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (30 sqft) - Car Sound Deadening Roller Metal Installation Tool 3 Pcs for Auto Noise Roller Car Sound Deadener Application Installation Tool Rolling Wheel Interior Accessories - Siless Hybrid 3in1 200 mil 25 sqft Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material --- ## 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.us/products/463695441-siless-max-120-mil-30-sqft-car-sound-deadening-mat](https://www.desertcart.us/products/463695441-siless-max-120-mil-30-sqft-car-sound-deadening-mat) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-24*
