So I’m looking to possibly ceramic tint my roof tomorrow. Also having the front two windows and even the windshield done. I know the roof is already tinted, but can anyone give me statistics on how much sun is actually coming through the roof currently with the factory tint? I’m curious how much it’s actually blocking because it feels like it does block a lot as it is and what is hot is basically ambient heat that doesn’t go away with any type of tint given it’s just the glass that gets hot and then radiates that heat out. I’d rather tint all windows in ceramic maybe as opposed to tinting just the front two and roof. Either option is about the same cost although roof is a little more overall. At this point, just wondering where my money is best spent on reducing heat inside the car. Is it by ceramic tinting the roof or by doing the back windows which I know aren’t ceramic and therefor blocking only a little light. Thanks in advance!
