Review: Exactly what i needed! - I recently purchased the Siless Liner 314 mil 18 sqft Sound Deadening mat and I am absolutely thrilled with the results. This product is a game-changer when it comes to reducing noise and improving the overall sound quality in my vehicle. The 314 mil thickness provides excellent sound insulation, effectively blocking out road noise, engine noise, and vibrations. One of the things that really impressed me about the Siless Liner is the price. Compared to other sound deadening products on the market, this one is incredibly affordable. I was a bit skeptical at first because of the low price, but after installing it in my car, I can confidently say that it is worth every penny. The quality of the material is top-notch, and it is easy to work with during the installation process. Not only does the Siless Liner effectively reduce noise, but it also helps to improve the overall sound quality in my vehicle. The sound deadening material creates a more acoustically pleasing environment, allowing me to enjoy my music and conversations without any distractions. I have noticed a significant difference in the clarity and depth of the sound in my car since installing the Siless Liner. Overall, I highly recommend the Siless Liner 314 mil 18 sqft Sound Deadening mat to anyone looking to improve the sound quality in their vehicle. It is a cost-effective solution that delivers exceptional results.

Review: Bringing a 1976 MG Midget to the modern world! - I've been restoring a 1976 MG Midget barn find. I bought some Sinless liner to help make the car rattle less and feel more solid. This product is easy to cut, easy to install, and extremely sticky. I used it to line the trunk, the interior, and even some under the hood of the old MG. The adhesive stands up to the brutal temperature of the engine bay, and when (by accident) some fuel spilled onto the foam, it didn't fall apart or turn to mush. Thanks to Siless, the MG now feels like a modern car. The floor pans feel much more solid, the doors make a heftier thud when you close them, and the trunk no longer sounds like a percussion instrument when you touch it. If you know what you're doing, this product will transform the feel of a car. I found that 36 sq ft was enough for my MG Midget, but for a bigger car I would want more. The pattern on the back helped me to cut perfectly measured squares and rectangles. The foam itself doesn't have a strong odor, it works super well, and has held up to several months of changing temperatures (in the Midwest US.)

### ⭐⭐⭐⭐ Decent deadener
*by R***R on October 19, 2025*

So, I'm using this in my jeep as the secondary layer on top of the butyl layer. I can definitely tell this will work. Adds mass and the thump test is audibly different. My issue is with sticking. I'm cleaning the metal with dawn and it's very clean. It sticks really well to your hand, but it's hit or miss on the actual sheet metal. I'm using a roller and areas are still unsticking. I recommend buying an adhesive spray to use with this to get the best results. If I did this again, I'd spend more money and buy the soundskins deadener. Premade combination of both materials.
