It's totally unnecessary! The purpose of not washing the car for a week after crystal plating is to better protect the crystals and make them completely crystallize. Once the crystal is solidified, waxing will not only protect the crystal better, but also consume the crystal. It is recommended to do crystal maintenance once every 56 months after normal crystal plating. If you are in Nanjing and need to do crystal plating, it is recommended to do it in Chimei, Nanjing, where the protection is in place and the effect of crystal plating is very good. The quality of this product is on the one hand, what is important is the construction of workers.

　　I am a professional in painting beauty. Before sealing and coating, there is no need to wax, because the enlarged image of the paint surface has many paint holes, just like our skin has pores, but the paint holes are very shallow. If you wax first, the paint holes will be blocked, which will affect the absorption of glaze and film. The wax will only adhere to the surface of the car paint and will not penetrate into the interior of the car paint, while the glaze and film will penetrate into the interior of the car paint to fill the paint holes, thus forming a protective film on the paint surface. To achieve the effect of protecting the paint surface, waxing in sealing glaze and coating will affect its penetration effect and its retention time. I wish you a new car every day and a good mood every day. I hope it can help you.
