I had my car tinted with 3M Crystalline almost 2 weeks ago. 40% sides and rear, and 70% on the windshield. The sides and rear look great, but I'm noticing the windshield looks hazy. I took it back to the shop, and they acknowledge that it looks hazy and will replace it. They gave me the option of going with the 90%, but I would like to stay with the 70% of possible. Do you think there was a problem with the installation or an issue with the film?
