Sun on the hilltops and long days parked outside
Open, elevated ground means plenty of sun. Cars that sit in driveways and open lots take direct light for hours, and that can fade clear coat on hoods, roofs and trunk lids. Horizontal surfaces usually show the damage first, as a dull patch that later turns into peeling.
Heat also makes plastic bumper covers and trim more brittle over the years, so a small impact that would have flexed a newer cover can crack an old one. When we see peeling or fading, we first check whether it is sun damage or a past repair that failed, because each needs a different approach and affects how neighboring panels are blended.
