I used peal n' seal for a while, but it started to fall off pretty quickly. If you go to parts express you can get some stuff called quiet kote, it's a nylon based (if I remember right) spray that works really nicely. I think it's like $15 a bottle and will do one layer on a trunk lid per bottle.
did u put it on correctly?did u wash all suface area where u were goin to apply it?...i'v deadened 3 cars and even my first car i had no probs...my guess is that u did something wrong and it was not due to the deadner itsself....not tryin to be a d ick btw..//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
i am getting ready to peel and seal my car a whole 200 ft^2 worth so i will start a thread to show the progress when i get it going. But it will be like a month or so.
The whole inside of my car is done in peel-n-seal nothing else, its on my interior page(3). It lays really good and is sticky as anything i've messed with. tried to pull a piece up, and it had such good adhesion that my paint started to come up with it. Also if i roll my windows up u can't even tell i have a system. Peel-n-seal is just plain awesome
