I would deaden the trunk, roof, and doors of my honda civic because my car sounds like **** right now! the trunk rattle is hoooooorrible. This would be awesome because I'm a broke azz college student and barely have money for audio equipment. Also I have never had the chance to mess with deadener, so it'd be a great oppurtunity to further my car audio knowledge. I would gladly write a review and recommend your product to my friends! Finally, I have terrible luck so it'd be cool if I won something for once lol.
