Just tinted my car. SoCal here. Did 35% suntek carbon line all around. And 80% ceramic tint on windshield. Cost me $169 for all around + $100 for the windshield. I did some research and the suntek carbon tint is a cost effective way vs ceramic. It is non metal so it doesn't reflect, and the heat reduction is within 3-4% of high end ceramic tint. I love the windshield tint, I don't even turn on ac it's so cool. No issues with HUD
