My friend's car is a white sagitar GLI. When I picked up the car, I asked the 4S shop if the white car needed waxing. They actually refused. I used it for several months and went to the car wash shop to ask the service staff. They explained that it was necessary to wax the white car. In fact, there is no color difference. On the contrary, white cars are most needed, because many hardware factories in Guangdong coastal cities have metal dust or colored dust falling on the surface of car paint, and black or brown ideas will appear if they are not cleaned in time. Some time ago, I took a closer look and found that there were many brown black spots on the surface of the car paint. I can't see them if I don't look carefully. I was thinking, who should I listen to? Is it necessary to wax white cars?

Two days ago, I accidentally went to a new Baoan store called Internet car maintenance and raised my questions. An engineer with over 10 years experience in automobile beauty told me that it is very necessary to wax a white car, because compared with metallic paint, white car paint does not add metal powder into the paint, so the toughness, adhesion, ultraviolet resistance and corrosion resistance of white car paint are not as good as metallic paint, and its service life and self-cleaning ability are also lower. So pay special attention not to use the wrong car wax when maintaining. Many car owners report that problems such as yellowing of white cars after waxing are caused by using the wrong car wax. Some beauty salons make huge profits by using wax from petroleum fractions. This wax will chemically react with white car paint, which will turn yellow after a while, leading many people to think that white car wax is wrong. There is also a low-priced car wax, which contains silicon, which will also cause the white car paint to turn yellow, so be sure to ask what wax is used before waxing. Don't be greedy and cheap when maintaining the car, and you will regret it if you hurt the car paint. According to some engineers, they used high-grade carnauba handmade wax imported from Kalumba, Germany. This kind of wax is pure natural and can even be eaten without any additives. The most remarkable thing is that they are all engineers, waxing by hand with their own hands instead of using machines. If there are a lot of additives and chemical elements in car wax, I don't think engineers will wax cars by hand. In addition, I heard that the biggest advantage of this wax is its decontamination function, which can easily remove all dirt on the surface of car paint, so riders with white car paint must pay attention to whether to use pure natural hand wax when choosing car wax.
