It is lifetime guaranteed. He does wagons too. I personally didnt go thru eclipse because they will only go legal. I even had an eye dr slip to get 20% tint and eclipse wouldnt do it. Im not to sure what he uses but he used the same stuff on his wifes odyssey that he put on my car, I know I have a friend that had it done by him 3.5 years ago and it still looks good.
