Yes, cars in America’s Rust Belt still suffer from excessive rust, although advances in automotive technology and materials have helped alleviate the problem to some extent. Here are some factors to consider:

1. Environmental conditions:

• Road Salt: Many states in the Rust Belt use road salt to de-ice roads during the winter. When this salt comes into contact with the metal surfaces of your vehicle, it accelerates the rust process.
• Moisture: The combination of snow, rain, and humidity in the Rust Belt can create conditions that promote rust, especially if vehicles are not properly cleaned and maintained.

2. Vehicle Materials:

• GALvanized: Many modern vehicles are made from galvanized steel, which has a protective zinc coating that helps prevent rust. However, if the coating is damaged (for example, due to scratches or chips), the exposed metal may rust.
• Plastics and Composite Materials: Some parts of modern vehicles are made of plastic or composite materials that will not rust. However, metal parts are still susceptible.

3. Maintenance Practice:

• WASHING: Regular washing, especially in the winter, can help remove salt and other contaminants that cause rust. Neglecting to clean the landing gear and wheel wells can lead to rust problems.
• Protective Coating: Applying an anti-rust treatment or primer can provide additional protection against rust, but not all vehicle owners take these precautions.

4. Vehicle Age:

• Older Vehicles: Older vehicles, especially those built before the widespread use of rust-resistant materials and coatings, are more likely to develop excessive rust.

in conclusion:

While modern vehicles are generally better resistant to rust than older models, cars in the Rust Belt can still develop excessive rust if not properly maintained. Regular cleaning, especially during the winter, and taking preventive measures can help reduce rust problems.
