High quality, super sticky, very effective
Style: 30 sqft
As long as the surface is thoroughly cleaned, these mats will stick to just about anything. They provide my car with a tremendous amount of sound dampening and have made riding in the car 10 times more enjoyable. I drive a Toyota Yaris and although the engine is built like it's meant to last forever (imagine that), the rest of the car is not of high quality. Which means we used to get A LOT of noise coming from the road, other cars, etc. After I installed these mats which, by the way, I wasn't able to install on every surface I wanted to install them on (due to lack of tools to be able to disassemble certain parts of the interior), the noise coming from outside the car is nearly completely gone. I covered the underside of my hood, the entire interior part of the hatchback, most of the floor in the trunk / spare tire well, and the entire interior side of the doors. The parts I couldn't get to (or didn't want to) were: the ceiling, underneath the driver & passenger seats, behind the dash and the floor for the 2nd row seating. As you can see I left a lot of surfaces untreated with this product AND STILL it blocks most of the sound. To note: people recommended getting the roller tools to help install these mats. I got a few of them in different sizes and they worked O K. Not because of the quality of the tool but because some places you need to install these mats in don't have enough clearance to use the tool. That being said, for the larger surfaces, the roller tools help a lot. Also I found it very beneficial to use aluminum tape while installing these. The tape I used is specifically designed for materials that undergo high temperature changes (like your dryer vents, etc.). This wasn't because the mats were not sticky enough but because there were some places I installed the mats with small gaps between them. I'd also recommend getting some kind of fluffy insulation-type material for large spaces that need noise dampening. Rock wool, for example, worked great for me. As an example, the interior sides of the 2nd row seating walls had large spaces between the plastic interior cover and the metal part of the car wall. I'd install the mats on the metal but was left with 6" - 7" of space between it and the plastic cover. I chose to fill those spots (and spots like it) with insulation which provided EVEN MORE noise dampening.

Best butyl out there.
Style: 30 sqft
If you want the money you're spending on equipment to pay off, you NEED to deaden sound! I've used every major brand and siless is my favorite to work with and the best value for your money, I'm not just adding weight, it's a thermal barrier and reduce outside noise. I turned a 10 year old, base model civic into what feels like a top tier Lexus . Does not offgas, no smell. Super easy to install. Make sure you get a set of rollers! They're required to achieve the advantages of this stuff, it MUST be adhered well and you don't want to tear the interior out twice.
