What to do if the surface of a white car turns yellow?
Cars need to run outside for a long time in the sun and rain. Over time, it is easy to cause the paint surface to lose its luster and turn yellow, especially the popular white cars can be seen everywhere on the road. This will not only affect the appearance of the car, but also affect its lifespan.
So what are the reasons for the yellowing of car paint?
Oxidation of car paint: The car parked outside is exposed to sun and rain, and the direct sunlight or rain washing all year round is particularly likely to cause the white paint to turn yellow, because there are a lot of ultraviolet rays in the atmosphere, and the rain contains a lot of acidic substances. Those are the factors that will accelerate the yellowing of white paint.
Not cleaning the car paint in time: the surface of the car paint is easy to be stained with dust, and it is inevitable that leaves, insects, bird droppings and other corrosive wastes that come into direct contact with the car paint surface will appear when parking outside. Finally it will make the car paint surface turn yellow.
The refinished-painting process is not good: the body painting itself is a very complicated process. During the process, different coatings are used at different stages, and different coatings form different paint layers. The process flow of the original car paint and the refinish car paint is still very different, so if there is a color difference during the later touch-up, the phenomenon of yellowing will gradually appear after a period of time.
After understanding the cause, how to remedy it?
Maintenance: Choose a reliable car beauty center, wash the car frequently, reduce the time of sun exposure, put on the car clothes for the car, and of course choose to park in the indoor garage as much as possible. If you are cleaning your car at home, don't use your own washing powder for the sake of cheapness and time saving, because they are alkaline and can corrode the car paint, so we must use a neutral car wash, which can not only clean the surface but also play a role in protecting the car paint, and there are wax components in it, which can improve the gloss of the car paint.
Polishing: Yellowing caused by car paint refers to the yellowing of the varnish layer, and the color paint layer is covered by the varnish layer, which is not in contact with the air and is not directly irradiated by ultraviolet rays. Therefore, polishing is to polish the varnish layer, to a certain extent. It can improve the yellowing problem, but it is not recommended to polish frequently, because this will change the thickness of the car paint and cause the car paint to lose its decorative and protective capabilities.
Repainting: If polishing still can't deal with the yellowing part, you can remove the yellowed paint and repaint it; when painting, you can choose a reliable painter and high-quality car refinishing paint to minimize the color difference.
So, if you don't want your white car to be so easily engraved with "traces of years", remember to give them regular skin care and maintenance to fight aging together!
