What causes rust spots to appear on the exterior panels of the C-Class?

Despite being a luxury car, some C-Class models in Pakistan develop rust spots on doors, wheel arches, and underbody areas, often due to exposure to humidity, road salts, and poor maintenance.

Rust develops when paint chips o r scratches expose the metal underneath to moisture and oxygen.

High humidity, rain, and road salts accelerate corrosion, especially in underbody and wheel arch areas.

Regular washing, especially after rains, and applying anti-rust treatments can help prevent rust.

Promptly repair paint chips o r scratches to block rust formation.

Underbody rust-proofing service at authorized centers is recommended in Pakistan’s climate.
