I'm running only side windows at 15% Avery Dennison ceramic tint... i still want to do the sunroof, back glass (in one full piece) and the windshield in a 70% but havenāt gotten around to it yet.
I will say, the side windows in ceramic make a difference, but the back glass, sunroof, and windshield need to be tinted too IMO in FL. Pic below is 15% with white seats so itāll be a bit lighter.
