Did the paint hurt the paint, Zhihu?

Automobile coating agent will cause some damage to automobile paint, but this damage is very small, which can be ignored compared with the advantages of coating agent. The composition of coating agent is different from that of car paint, which will lead to different shrinkage rates of coating agent and car paint. When the coating agent penetrates into the car paint, it will cause certain mechanical strain to the car paint due to different shrinkage rates. However, coating agents have many advantages. The first is the long duration. Generally, the validity period of film coating agent can be maintained for about one year. Moreover, the coating agent is the cheapest of all automobile beauty products (such as waxing, glaze sealing, etc. ). Secondly, after using the coating agent, daily maintenance such as car washing will be reduced, which indirectly saves time and correspondingly reduces the cost of car maintenance. After painting, put a colorless and transparent glass film on the outside of the painting to make it look brighter. The most important thing is that the coating agent used is genuine. If inferior coating agent is used, the damage to car paint will be even greater. Especially now, the automobile beauty painting market is very chaotic, and it is easy to buy fakes. So if you buy it, you must buy big-name genuine products.
