I haven't had a problem with the roof line. I've gotten a few nice rubber marks up there, but those have cleaned off. The area of my hood that has suffered from chips is just above the headlights. My clear bra runs down the lower side of the car just below the crease in the lower door line and ends behind the rear tire. It's done a good job, but I should have run it up on the shoulders in front of the rear tire. My windshield looks like it has been through a sand storm though. I'm thinking about trying some glass polishing compound to see if it improves it.
