Has anyone used this for noise dampening?

Your link wouldn't open for me. However I gotta say that Sonic Electronix NVX brand has some stuff that looks really nice.

I've used many but not that one. You don't want to skimp on that product after tearing apart your entire car to apply it. Sound Deadener Dhowdown CLD tiles or second skin Damplifier are the two best I've used. For a lightweight alternative Sonic Barrier lightweight vinyl, part number 268-035 from parts express.
