Sound deadner & heat barrier?
Cudachick1968 ~ Thats the stuff! I used it on my Duster. Happy as can be. An extra step is adding the ensolite. That stuff works well. Rick at RammAudio is great too. I never used the Home Depot stuff. Always worried about using products other that what they were intend for....But a ton of people swear by it. Cost is 4 time less.
But I would do it all again with the RammAudio!
