Are you asking about window coverings? Or coatings as in tint film? A friend of mine put the clear ceramic film on the windshield of his truck and he highly recommended it to me. Says it really makes a difference. I'm going to order some and give it a try. I can never seem to find anyone that does it professionally that isn't booked out for weeks. Kinda hard to make an appointment that far out while on the road.
