Awesome product. Installs very easy. Really made my cab quieter in my 99 7.3 Powerstroke. Tech tip leave it inside somewhere cool until install because it gets very mushy and messy when warm.

I have been in the miserable world of custom cars for over 25 years. i only found a couple honest knowledgeable reviews. I doubt this qualifies as knowledgeable but, I do have some feedback. Does it work? Yes, it does function as sound deadener fairly well. For what you pay this is pretty good. Is it Roadkill or Dynamat ? Nope, that in my opinion is another class of product. I used this on a 77 Toyota land cruiser that has a total budget for upgrades and has a must have list. To cover the same square footage would have been nearly double the money in my preferred brand. I sat down and read the reviews on Amazon and a few other sites. After I hadthe cargo area done I was overall happy with the purchase and continued to finish out the entire vehicle. The first big difference is the adhesion. It is noticeably less than a name brand and requires a bit more surface prep and cleaning to get the maximum sound deadening. That is one of the biggest mistakes you can make with any brand sound deadening product is to not get it stuck to the surface with as few and as small of an air gap as possible. Getting this to stick in all the little cracks without some release takes a bit more work. Is it as dense as a name brand ? Nope again. It is about 80-85% as dense as a name brand . You can hear it after it is applied and feel it when it comes out of the box in weight. The weight is a bonus as it is lighter and i would use it again in a hot rod or go fast project where you were trying to bring down sound while not trying to turn the vehicle into a brick. i did not have a way to compare the heat loss from the application against another brand at the time of this review. I would suspect it to be about the same in that aspect as well in being well sufficient but, not quite as good as a name brand. It does seem like I am hating on the product but, in fact I am not. i would use it again and will for the price. Overall it is a 3.5-4 star product. If value it on price equal to performance it would easily be 5 stars. I gave t the review and rating I did based from use of top tier brands compared to this product. If you are looking for the maximum sound control and heat loss buy a name brand and apply it properly but, have deep pockets. For a budget minded person looking for significant results and still have some money for other parts of your project buy with confidence. I will reiterate This product does take a little more elbow grease to get proper adhesion, buy a good set of rollers and wedges and make sure it is stuck down. No replacement for good prep and proper installation.
