Review: Highly recommend!! Easy to use and good and sticky - Update 12-10-23 ok so for some odd reason we are having some issues this year with rats in general. Likely all of the construction in the area not really clear. This is the first time since I moved in 8 years ago. That said I have to absolutely commend this product. It literally saved my ZL1 wiring. I used it for noise and noticed some trash and such in the cowl of the car. I opened it all up and found they had chewed up some junk and tried to get through the mat and they failed!!! I'm so pleased that they only chewed up the mat only a little bit but it absolutely protected any access point to wires or the interior. It took me a couple of hours to check the entire car over and really only the spots where the mat was laid were touched. I don't know if they ended up getting hurt by the metal in the mat(don't care either) but I am so very relieved no damage was done. I can easily replace the one small section. Last photo loaded. Again I realize I did not use this product for the intended purpose. I am however going to buy the new one with 3 layers for another car. Highly recommend. Easy to work with for sure. Not overly thick. For my application it did not deaden the noise as much as I had hoped. I used it within the cowl of my ZL1 to try and limit the noise from the supercharger lid spacer. I know not really intended purpose but compared to some of the other stuff out there it was worth a try and it is not obnoxious silver. Since I was able to get it into many of th bends it was easy to work with using just sissiors remove backing and lay it down. Personally I bought way to much so I will use it on other applications at some point. Pay attention to the into cost which is why I ended up with so much. 😂 Review: Good adhesion - Been buying this for couple years now for multiple projects including jet boats..love it ## Features - ★ Siless VIBRO 50 mil is ultimate quality sound deadening insulation.

No decal present in any box I've used.. **Q: Will this work on the inside walls of a cargo van? reduce noise/vibration? insulate? reduce heat? repel water?** A: Thank you for your question. Siless Black 50 mil will reduce noice/vibration. Together with Siless 157 mil closed cell, installed as a second layer, will insulate/reduce heat, and will provide with weatherproof properties. **Q: what is the weight of a box** A: 15-20lbs! **Q: Can it be used uder the hood and will it hold up the the heat of the engine?** A: Thank you for your question. Siless Black 50 mil Sound Deadener Mat has a working temperature range from- 50 degrees to 210 degrees F. Also, for short period of time it would withheld heating of up to 375 degrees F. We won't recommend installing under hood in the engine compartment due to temperature constrains. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly recommend!!
