You should definitely go with Second Skin Damplifier. Its the bst stuff I have used by far. Its cheap, holds great and is really easy to apply. I have 120 sq ft of reqular Damplifier, 72 ft of Damplifier Pro and 32 sw ft of Luxury Liner Pro and my ride is whisper queit. You can buy it online direct from the company at: http://www.secondskinaudio.com
