I have a 2010 Toyota Corolla in metalic grey color. I am planning to get a california legal tint (back three windows) soon. Anyone knows which ceramic tint works best for it? I have narrowed down the choices in between Formula One Pnnacle 35 and Huper Optick 40. Please let me know your opinons and suggestions. Thank you. If anyone has either one of these two films applied to his/her car, please upload a photo if it is possible.
