Everybit as good as the more well known products

The following review is for SDVK4, which is a part of the bundle you are viewing.

This came free with a bundled purchase,.. and I also purchased some Rattletrap Extreme as this wasn't enough for the car. I was expecting this to be mostly unusable due to the Name.

I was wrong.. it was every bit as good in thickness and adhesion as the more expensive brand I had bought. So if you can get this cheaper than other Sound material,.. go for it.

NVX SDVK4

The following review is for SDVK4, which is a part of the bundle you are viewing.

Works great at a great price. I have it under my trunk lid and it keeps it from rattling too bad.

Good product, not the easiest

The following review is for SDVK4, which is a part of the bundle you are viewing.

Used a few sqft of this material, along with the equivalent from Streetwires (PartsExpress) and a ton of Peal 'n Seal (Lowe's) for the rest.

I would say that Peal 'n Seal was the easiest to apply, but also the thinnest (an cheapest). So if you are doing some serious job you may want to double or triple the layers.

The NVX material was the thicker of the three I used, and once it's glued it stays soft which is very good. But beware, you will never get it off again. The only thing I would reproach is that the aluminum is quite thick, which makes it hard sometimes to comply with shapes. But it is good to fill in big gaps or openings and add some rigidity.

My preferred material is the Streetwire stuff, which is a bit cheaper. It was thick enough and compliant enough to make it really easy to install and it sticks like crazy while being forgivable if you make a mistake.

Have fun!!!

Great product!

The following review is for SDVK4, which is a part of the bundle you are viewing.

This is the first sound dampening material that I've used so far and I have to say that I am quite impressed with the product. I used it to reduce the vibrations generated from my sub at the back of my car. Since then, sound quality has improved considerably. For the price, I strongly recommend this product.

works great

The following review is for SDVK4, which is a part of the bundle you are viewing.

Less weight than other sound proofing I have used, cuts easy and with a hair dryer it will mold to any contour .

Perfect kit foe speaker installs or a single door.

The following review is for SDVK4, which is a part of the bundle you are viewing.

This deadener works wonders for vibration and outside noise. It is thicker than Dynamat and will eliminate that horrible resonance caused by lower frequency notes transferred through sheet metal and rattles in plastic. It also improves sound quality and SPL.
