Will Domestic Cars Rust?

Domestic cars can rust, but not all domestic cars will rust. Reasons related to the body design itself: Some cars are not designed with complete structural considerations in mind. There may be sharp corners or dead angles in the sheet metal, leading to insufficient electroplating of the car body. Alternatively, the process design may not have been fully considered, resulting in incomplete or insufficient electroplating and wax injection processes for the sheet metal. Reasons related to the car owner: Car owners may not pay enough attention to paint surface damage. Over time, paint surface damage can lead to rust, which can then spread and cause more extensive damage to the entire paint surface. Reasons related to the manufacturer: Some manufacturers, in pursuit of higher profits and cost savings, use ordinary sheet metal. This can cause cars that should remain free of serious rust for 6-7 years to develop rust within one or two years or even sooner, affecting driving performance.

Will domestic cars rust? Let me share from my personal driving experience. I've driven a domestic car for several years, and initially, I did notice some rust spots on the chassis and door seams, mainly when I didn't wash the car promptly after heavy rain. Later, I developed a habit of drying the car body after each rain, especially around the wheel arches and chassis area. I also regularly visit the repair shop for anti-rust wax treatments, which only need to be done every six months. Nowadays, new domestic cars like Great Wall and BYD use advanced coating technologies, making them much better in quality, but older models require more attention to maintenance. In humid areas, such as during the southern plum rain season, I avoid parking under trees or near puddles to prevent accumulated water from leaves causing rust. Overall, rust can happen, but with regular care, it's not a big issue.

From the perspective of automotive craftsmanship, will domestic cars rust? I've researched material development, and currently domestic cars mostly use galvanized steel sheets and advanced coating processes, which offer significantly better corrosion resistance than traditional steel materials. Mainstream brands apply cathodic electrophoretic coating during manufacturing, immersing the car body in anti-corrosion solutions to form a protective layer that effectively isolates moisture and oxygen. I've also noticed that during new car launch testing, vehicles undergo months of simulated humid and hot environments to ensure rust resistance. However, in real-world usage, if the paint surface gets scratched or the chassis is damaged exposing bare metal, rusting can still occur. Therefore, when choosing a car, prioritize models with anti-corrosion treatment and avoid driving on salt-covered roads. Maintaining intact paint surfaces is crucial.

As someone who frequently maintains cars, I believe the rust risk of domestic cars can be reduced through simple maintenance. Always dry the car body after washing, especially the corners and undercarriage. Anti-rust spray works well for wheel arches, and I use it once a month. In areas with snowmelt agents in winter, promptly rinse the chassis. Park in dry, shaded areas to avoid rain and water accumulation. While new domestic brands have improved their processes, older cars require more frequent inspection for scratches.

I've been driving for decades, and the rust issues with domestic cars have indeed become less common than before. I remember that older models 20 years ago were prone to rusting through the chassis, but with the widespread adoption of new technologies, anti-corrosion standards have improved. New cars now use better materials and coatings, and the testing is more rigorous. I've personally owned several domestic cars, and the corrosion resistance has noticeably improved, but it's still important to pay attention to environmental humidity.
