So, I've noticed after installing a fiberglass headliner, the sound dampening of it is nil. In fact, reverberation of noise has gotten worse. Luckily, it is very easy to drop back down and make some changes.
Has anyone with an SW installed some type of very, very lightweight sound and/or vibration dampening on the roof/ceiling?
I was looking at Cascade
, but I can't determine what they have that fits the bill. The lower body portions of my truck are lined with Extreme Dynamat, and while it works well, it's extremely heavy. So it's not going up there.
I guess a foam based, vinyl product makes the most sense. Lightweight and absorbant.
