Great product. Best value i could find
Model: SLH20025
I'm using talk to text, so forgive any grammatical and spelling errors.
I ordered this product after doing a bit of research on sound dampening materials. I had been doing car stereo for quite some time since my teens. Itook a break for 20 years or so. I'm now 40 and back in the day there was dynamat. And that was about it. as irecently bought a new 2017 F350 crew cab. I wanted to put in a new stereo system and being that it was my dream truck. I was going to put in my dream stereo. But before I could do that, I needed to start with the sound deadening. I looked into today's leading product and found a company called resonx. Had taken their place as king of the hill in sound deadly. I researched their products and found the materials they were built from and Silas was the closest match at the best price I used Silas Max. First, then Silas 3 and 1 hybrid over that on all exterior panels. Then, on the interior panels. I used the 3 and 1 hybrid . on the floor I used Silas Max. Then, the 3 and 1 hybrid, then Silas liner over that the car is incredibly quiet . As far as sound dampening and deadening, it works very well for the money really can't beat it. Do your homework no How and where to apply it? And you really can't go wrong or about $400. I did. What would have cost me easily? Two thousand in other brands highly recommend the product prep work.Is everything do your homework?Do it right and you will be happy with this stuff

Not simple, nor easy
Model: SLH20025
I wanted to add sound proof material to the bare metal areas on the floor of my Toyota Tundra. The area behind the front seats had a haphazard application of sound deadening material. There were several complications to the project which may come up in other vehicles.
First is the floor covering which had plastic pillars underneath to support any weight on the cover. The sound deadening material had to be cut out so these pillars would rest on the bare metal of the floor. This required a lot of cutting with a utility knife and at times heavy scissors. The instructions say to make a template before cutting the material and I did this for the driver's side. This doubled the amount of time needed to install it. On the passenger's side I laid the rectangles of material with the backing on and pressed the floor covering onto the material. This showed where the support pillars were, which I then cut out.
Second is peeling the backing off the material. This can be very difficult as the adhesive sticks to it. The backing came off in multiple pieces and sometimes took 5 minutes for one piece. They say to wear gloves when handling the material but this is impossible when trying to get the backing off.
Third is pressing the material onto the metal. The instructions say to use a roller, but this was impossible for the irregular surface I was working on. The hand is the best tool to press the material on.
The material seems to be of high quality and I expect it will reduce the road noise in the cab.

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.
