After reading a bunch of bad, and good reviews, i have decided to just use it on the floor of my car. Everyone who has put it on their roofs, or doors have had problems, but with it on their floor, it has been ok. Right now i dont have much audio in my car, and my main goal at this point is to try and kill road noise coming in from my car. It was hella loud, and then got even more loud once i dropped it. Then once i start building my audios, my floors will already be deadened, and i will just need to do my roof, and doors. Anyway, what is it called? i searched teh website for peel and seal, and peel and patch. I even asked the guys at the depot, and they failed me as well. Although i told them it should be in the heat/air duct section, not the roofing section, which i later found out that is where it would be. Any help fellas?
