Frequently Asked Questions (FAQ)


Surface prep is key. Clean the metal with denatured alcohol first. For a permanent bond, use an NVX SDRLR1 roller to press the butyl into the pores of the metal and remove air.
Rattles happen if the mat isn't fully fused to the metal. Ensure 100% contact. If issues persist, add a second layer of NVX SDSK2 or check for loose factory clips.
No, but it helps. NVX SDSK2 is thick (90mil) and more flexible when warm. A heat gun makes it easier to mold around curves, ensuring a tighter, more effective seal.
Since it's a heavy 90mil, use a sharp utility knife on the foil side. For the cleanest cuts and safest install, we recommend using the NVX stainless steel utility knife.
This kit is for two doors. For trunk rattles caused by subs, you need more mass. Upgrade to the NVX SDTK20 Trunk Kit for 20 sq. ft. of the same premium 90mil material.

Nice Wiring Kit

This is a nice quality kit at a fair price. It had everything that was needed to complete the task.

I had purchased another kit that I really wasn't happy with, and decided to purchase this one. I liked the attention to detail in the preparation of this kit. Recommended.

Works pretty good

I bought this product for my trucks doors, and I noticed it's thicker than other sound dampening material I've used before that I paid a lot more for. This is a great product at a great price

Easy to use, good performance!

We used this in conjunction with a component speaker upgrade to a 2003 VW Passat. This material is simple to use (if you can work scissors and peel off adhesive backing, you can handle this stuff!), and you can easily cut it to any size or shape to fit your particular vehicle. Installing this material was the easiest part of our whole car audio upgrade project!

EXCELLENT

Very nice sound dampening material easy to install and gives a great added depth to the sound of yr system, deeper bass and mids and also minimizes the resonance of the factory locations

Nvx = quality at the best price.

I'm so happy with all my NVX products. They are always the best in quality and price. No smell and if it's not a lot you can apply it without a roller. (I used my hands and the back of a screw driver to really smooth it out)
