UV rays can damage the car’s paint, clear coat, and interior materials, causing them to fade, crack, and deteriorate.In addition to causing cosmetic damage, sun damage can also lead to more serious problems, such as rust and mechanical failure.

Rust can occur when the sun’s UV rays break down the car’s paint and clear coat, exposing the metal underneath to moisture and oxygen. Mechanical failure can occur when the sun’s heat causes the car’s rubber and plastic components to deteriorate.
