My installer was confident in doing the windshield and quoted me at $70 extra to do it. I declined since I didn't want to take a chance. I ordered the covercraft windshield cover instead for when my truck sitting in the sun.I am planning to get 70% for all around the windows includes sunroof and windshield for heat rejection. Still doing research for brands. Was trying to do 3M crystalline, unfortunately the installer won't do sunroof and windshield...
