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!

Absolute gamechanger!
I'm one of those people who research for a week then buy the best product possible. Often times, if you research enough you can find one of those companies that is putting out an insane product without paying for the name. This is one of those products. I needed a solution for my new system in my car. I stumbled on an experiment from an independent rival company that tested the top brands. This 50 mill version was a slam dunk. Performed better than 90% of brands and even a ton with thicker products. I installed this in my whip and it definitely steps up to the plate. It does a fantastic job sticking to things and easy to put on in tight places. My car sounds like Bose QC35 headphones on a solo camping trip. It's a much different experience from my noisy old car. Did I mention that I have a moonroof and roof rails. Still quiet though. I can honestly say that, for the rest of my days driving future cars, one of the 1st things I will do is pull out all the interior and put in Canopus sound deadening. Save yourself the time. Add to cart. Coming from some random midwest dude... you're welcome! #cheers

Really good sound insulation. Lowered noise and vibration under the hood.
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.

Easy to use
This product is easy to use. The adhesive is sticky and holds tight. the product is very dense and will provide sound deadening. You can easily cut this to size. Works better then used with the rollers.

Good stuff!
Great stuff for the money. Takes the rattle out of an old truck's door panels. Easy to work with and sticks well.

Very effective, great quality!
LOVE THIS PRODUCT! Every once in a while a product is so good, I actually want to give them props. This is one of them.. Really deadens panels, stops vibrations and ringing. Quality is fantastic. Great adhesion, or initially pulls off it you make a mistake. I will buy more.

Great For DIY Boom Boxes
This is exactly what I was looking to put inside of my DIY boombox. Easy to cut with scissors or razor, very sticky backing, light weight, and makes my box sound better. For this price it works perfectly. Great bang for your buck. Will order again.

Prodotto validissimo, facile da modellare e applicare. Utilizzato per isolare le portiere della mia auto. Il risultato finale, unito all’upgrade degli speakers, è stato eccellente.
