Sedan cars require long-term exposure to the sun and rain at Mercedes Benz, which can easily cause paint loss and yellowing, especially the popular white sedans found everywhere on the road. This not only affects the appearance of the car but also its lifespan.

So what are the reasons for the yellowing of car paint?

Car paint oxidation: Cars parked outside are either exposed to wind and rain, or have experienced exposure to sunlight and rain. The constant exposure to direct sunlight or rain can easily cause white paint to turn yellow. Due to the presence of a lot of ultraviolet radiation in the atmosphere, rainwater contains a lot of acidic substances, which are all factors that can accelerate the yellowing of car white paint.

Long term non cleaning: The paint surface of the car is simply stained with dust, and it is inevitable to see corrosion debris such as leaves, insects, and bird droppings that come into direct contact with the paint surface when parking outside. Long term non cleaning and maintenance can cause the paint to turn yellow.

Poor paint repair process in the later stage: Body painting itself is a very complex process. During the body painting process, different coatings are used at different stages, and different coatings form different paint layers. There are still significant differences in the process flow between the original car paint and the repair paint, so if there is a color difference during the later repair paint, after a period of time, the phenomenon of yellowing gradually occurs;

After understanding the cause, how should we make up for it?

Maintenance: Choose a reliable car beauty center, wash the car frequently, reduce the duration of sun exposure, and be able to dress your car. Of course, try to park in an indoor garage. If you are cleaning your car at home, do not choose your own laundry detergent directly for the sake of being cheap and saving time. As they tend to corrode the car paint due to their alkaline function, we should use a neutral car wash solution. It not only cleans the surface of the car but also protects the car paint, and there is also wax content inside, which can improve the glossiness of the car paint.

Polishing: Yellowing caused by car paint refers to the yellowing of the clear paint layer on the surface, which is covered by the clear paint layer and is not in contact with air or directly illuminated by ultraviolet light. Therefore, polishing is the polishing of the clear paint layer, which can relatively improve the yellowing problem. However, frequent polishing is not recommended, as it can change the thickness of the car paint and cause it to lose its decorative and protective ability.

Apply and spray from the beginning: If the polishing still cannot solve the problem of yellowing, you can remove the yellowed paint from the car and spray from the beginning; When painting, reliable spray painters and good car repair paint can be selected to minimize color differences as much as possible.

So, if you don't want your own white sedan to be simply engraved with the marks of time, remember to give them regular skincare and maintenance to fight against aging together!
