Review: Decent alternative to Dynamat - Doesn’t have an odor it’s extremely sticky. I worked with it on a nice day where it was in the 70s outside. Make sure you have a couple extra blades for a razor knife unless you have utility scissors regular household ones don’t work very well. This stuff is tough. You get a considerable amount of material to work with I did two doors and most of the spare wheel well in my trunk of my Mk7 VW Gti. It doesn’t really make that much of a difference by itself. If you wrap the speaker hole of a door before you install it this will help with vibration and improve the quality of your speaker. Pretty good value for what you get. Box had pretty good weight to it. I recommend getting a roller to smooth it out and you really only have to just wipe the panel off unless it’s dirty. This stuff will stick to anything. My only complaint is that it’s a bit thin otherwise does the job well!
Review: Works as described - Easy to apply to spare tire well of Lexus RX350. Reduced resonance. Next step is to add closed cell foam to further reduce sound coming into cabin.

### ⭐⭐⭐⭐⭐ Really good sound insulation. Lowered noise and vibration under the hood.
*by Z***O on September 7, 2024*

Really good sound deadening material for my Buick. There are several things about this I like that I liked. - It's made in the USA, which shows in the quality. - Speaking of quality, the butyl material has very good adhesion properties. My hood has some indents in it for the heat insulation to fit into and the material stuck and conformed to the indents. - I was able to use scissors to cut to shape. In most situations I had to use a knife on other brands. So easy to cut and install. - The roller I used did an excellent job. The foil was strong enough that the roller didn't rip the foil on top of it. I also had this issue with some other brands. All in all it does a very good job. The sound of the intake and loud injectors all went down significantly. Cruising on the highway also showed it lowered road noise from the front wheels. Even with the amount I used I still have 3 sheets left. Definitely a good buy.
