How Many Years Will It Take for a Car to Rust After Body Panel Repair?

[JaxsonLynn]

After body panel repair, rust generally occurs within 2-3 years, primarily because ordinary steel plates are used for the repair. Below are relevant details: Thin steel sheets: The outer shell of a car is made of thin steel sheets, which undergo comprehensive anti-rust treatment during manufacturing. If the car hasn't been severely damaged or undergone welding repairs, it won't rust. Therefore, while body panel repair is possible, welding should be avoided as it damages the anti-rust layer. Once the anti-rust layer is compromised, it loses its protective function, and cars used in coastal areas may rust within two to three years. Automotive body panel repair: This refers to the repair of a car's body after a collision, encompassing all tasks except for anti-corrosion and decorative spray painting.
