My '18 Limited is in the shop right now getting tinted. I'm having ceramic tint on all windows and sunroof panels, and a windshield strip. He didn't recommend doing the sunroof, saying something about the curvature of the glass and possibility of the glass shattering? I'm having it done anyway, way too much heat comes through now. He said he could do the entire windshield BUT if it needs replaced from cracking (in AZ windshields crack a lot from heat, I had 3 windshields in one car within 3 years) insurance covers glass but not tint (which was $200 to have done). I already have a tiny crack and lots of pitting so he suggested the strip for now, then full tint if/ when the windshield is replaced (which he can do, applying the film before installing the glass). He's doing 20% in front windows (just higher than legal) and 15% on all the privacy glass (so it's a uniform look). I've had "limo tint" in previous cars and during the day it's fine but at night it's very hard to see through the back windows so not going that route.
Total price for removing existing tint from 2 front windows and doing ceramic on all windows, sunroof, and windshield strip: $825 (plus tip of 20%), so just under $1k. I'll update how I like it when I get out back. Going back up to 110 in Phoenix by tomorrow, just in time!
