A lot of materual

The following review is for SDDK12, which is a part of the bundle you are viewing.

Ordered this for my F Super Cab. I just wanted some material to apply to the inside of the door skins. It is a lot more material than I needed. Ford already has a small amount of sound dampening material. It did quiet the interior as expected. Great product. Came with no instructions. I just used some alcohol to clean the surface first.

Decent Dampening

The following review is for SDDK12, which is a part of the bundle you are viewing.

I have had this for almost three months on my trunk lid and it has made a big difference. The rattling is not as bad as it used to be and it made a difference inside the car.

DON'T buy this if you live in arizona because the heat is too much for it.

Impressive product

The following review is for SDDK12, which is a part of the bundle you are viewing.

This is a very stout, impressive product. It feels thicker than the famous competition and there is no smell to it. The sheets you get are sort of a long/narrow size, so they are great for running vertically up the doors and on the outer door skin. You'll definitely want a source of heat when working with these and really, there isn't a better value for the kind of product you are getting here.

This is great material for a great price. Ive bought multiple nvx dampening products and have been pleased with everyone. This this easily applied with a nix roller and contains the perfect amount plus some to use on your doors.

Great for Rattles

The following review is for SDDK12, which is a part of the bundle you are viewing.

Installed this stuff in my front doors and enough for the speaker area in the rear doors. It only slightly reduced the road noise in my car, but tightened up the bass and reduce rattles by a huge degree. This stuff is easy to install and can often be bought on sale.

NVX SDDK12

The following review is for SDDK12, which is a part of the bundle you are viewing.

Excellent sound deadener for the money, very thick, no smell once applied, super tacky and sticks even to dirty surfaces. Applied in my doors it made a big difference inside the car, applied in the trunk the bass sounds much better inside but it didn't stop my trunk from flexing and sounding like it's about to explode. All in all excellent product and would definitely recommend!
