Signs of Wear and Replacement:

Over time, plastic trim components can become brittle due to prolonged exposure to sunlight (UV radiation) and temperature cycles. Common forms of damage include broken retaining clips (often occurring during maintenance or removal) and surface cracking. Replacing a damaged or missing hinge cover is recommended to prevent water and debris from contaminating the hinge mechanism, which can lead to binding or rust over time.
