While I have used fatmat for the last five years! It's been great. But this year make's the fifth year and it started to peel off on the roof but not much. the rest of my truck was still in place. But this was the the hotest year ever it peeled off when it was 105 degrees out side sun hitting it all Day! But it is cheaper than Dynamat I just bought 200ft for my van! Great stuff! Fact: Dynamat did the same thing in my friends SUV in the summer in the heat! both product are great! Dynamat is thicker but fatmat you get more for the money so you can do 2 to 3 layer's!
