It is also not the tintshops warranty, it is the brand of tint they use. That way if it does have to be fixed, the company pays for it, not the tint shop. Some of the best on the market is Johnson, & Llmar! It is really hard to find someone using Johnson, my old tinter quit and that is all he used. He had a truck with tint that had been on it 8 years, and it still looked like the day it was put on, awesome tint.
