Problems solved by technology

[0007] Disadvantages: Insufficient durability is the most prominent disadvantage of waxing
[0012] Disadvantages: Due to the erosiveness of the glaze, the car after the glaze treatment cannot be changed to waxing or other methods for paint surface maintenance, and can only continue to be glazed
[0015] Disadvantages: Expensive, too short
[0021] In order to change these defects of the traditional car paint surface, researchers have made unremitting efforts for a long time, and some products that treat the symptoms but not the root cause have appeared one after another, such as car paint coating and crystal plating. These products have short aging periods and are not durable. Due to defects, it cannot be applied by automobile manufacturers
