Great Product Highly Recommend

I used the NVX SDBTK20 (91 mil) on my previous truck and just used the Ultra Thick SDBPRO20 (4.5 mm) on my Ranger Raptor. Over twice as thick and does a great job. Applied easily and definitely gives the doors a solid feel.

NVX thick sound deadener

This pack of sound deadening sheets is thicker and helps stop the vibration from my system. I would definitely recommend this pack of deadener if your trying to find something to stop the vibration and rattles. Good price for what it does!

The best sound deadner I have found next to Second skin!

I love this double thick deadner,it's like the Second Skin brand,but cheaper in price. Really heavy and helps stop rattle,and deadens road noise better than regular deadner. I'll keep buying this and the NVX silver deaner is thinner for places ths is too thick.
