Understanding Rust and Its Effects on Cars
Rust is a type of corrosion that occurs when iron or steel is exposed to moisture and oxygen. It is a natural process that can occur on any metal surface, including cars. Rust can cause a range of problems, from minor cosmetic issues to major structural damage. In severe cases, rust can even lead to the failure of critical components, such as suspension and steering systems.

Rust can spread quickly, and if left untreated, it can lead to costly repairs and even render the vehicle unsafe to drive. By addressing rust spots promptly, car owners can prevent more extensive damage and save money on repairs.
Common Causes of Rust Spots
