Don, I disagree. First of all I live in northern Ohio so I don't have to explain the weather conditions that we ohioians endure. I'm not saying use the heat gun and melt it just make it tacky and stick it and roll. I've had this installed now for 4 years triple layered doors floor hatch and top. And I can honestly say with the extreme cold it has not peeled or fallen off. In fact I mistakenly applied some outside the panels which I cannot remove. It is permanent. For a lot of us on a budget (enforced by the wife) dynamat, fatmat etc is out of the question. If peal and seal is applied correctly it can do just fine. No marketing schemes or scientific research just common sense. And by that I mean cost. 1 roll of peal and seal 33 1/2 ft. By 3ft. At 41mil was 86.00. I used two rolls. triple layered. It more than justifies itself through cost. Now I must emphasize on installing it correctly or ur right it will separate as I have found out through trial and error. The surface must be prepped free of dirt and grease and oils. Prepsol works good. There's no odor even on the hottest days or even when the car has set for an hour running. For me and many others this product is an affordable solution to deadening especially when you can get 67ft by 3ft wide for around 200.00 and simply double layer or triple if u want that thickness. I have no rattles and sound is almost completely encompassed inside the car especially the bass which ideally is the goal for good sound is it not?
