Causes of Rust Spots:

Humid and Coastal Environments: Areas with high humidity, such as Karachi, are prone to rust development. Salt from coastal air accelerates the oxidation process.
Paint Damage: Small chips o r scratches in the paint create an entry point for moisture, leading to rust formation beneath the paint.

Prevention Methods:

Regular Cleaning: Washing the car frequently, especially the undercarriage, helps remove salt and dirt buildup that can cause rust.
Rust Proofing: Applying a rust-proofing spray to vulnerable areas like the undercarriage and wheel wells can significantly reduce the chances of rust formation.
Touching Up Chips: Address any paint chips o r scratches promptly to prevent water from reaching the metal surface.
