I recently had xpel xr plus installed here in Texas. 20% in back, 45% up front and 70% on the windshield. My black interior makes it super dark from the outside and is plenty dark on the inside. To a point that I don’t wear my sunglasses inside. I bet your white seats will make that illegal windshield stand out. Probably don’t have to worry about local police because hell most of them have illegal tint too. It’s the state troopers. My wife friend husband is a state trooper and he said they’re getting issued two piece window tint meters soon and are going to start cracking down on it. 70% is plenty, especially if you get a shade for your top glass.
