First of all, paint products are different from car wax in composition.
Aside from the false name, the real coating is to form an inert film on the surface of car paint through inorganic silicone-fluorine polymer materials, which can reduce the discoloration and corrosion of car paint.
It's quite understandable It's just that some friends' cars often park outdoors or under trees for a long time. Do you see those cars are not so bright?
On closer inspection, there are some ugly marks on the paint. In fact, car paint has been oxidized and corroded by acid rain, ultraviolet rays, bird droppings, shellac and so on.
The composition of coating products takes fluoropolymer as an example. Liang Lei et al. published a paper "Preparation of fluoropolymer emulsion and its application in solid-liquid interface" in Material Guide magazine.
It says: fluoropolymer has good thermal stability, can play the role of anti-oxidation and anti-aging, and has strong adaptability to the environment.
For example, 1965 found a template sprayed with fluorine paint in Florida, USA. After 35 years of exposure, it is still similar to the new product.
Coating can improve paint performance and increase hydrophobicity.
In addition, the coating can not only protect the car paint, but also improve the performance of the paint surface and increase the hydrophobicity and smoothness of the car paint.
Some friends may not know what use the hydrophobicity and smoothness of car paint will have. Simply think of it this way: after painting, dirty water and dust are not easy to attach to the car paint.
You were driving in front, and a car ran into a dirty water pit next to you. It drains more water when it hits our car, so the car is relatively less dirty and easier to wash.
Hebe Tien also published a paper "Application and Prospect of Coatings on Automotive Paint" in the magazine "New Material Industry".
It says: After the car is painted, the dust can be easily removed in the process of getting wet or washing the car, and the expected cleaning purpose can be achieved with little water.
So in general, the practicality of the painted car is still ok.
The coating can be made by itself, and the operation is simple.
Besides, we don't have to go to the store to do the coating now. We can put it aside and do it ourselves. The price is only a few tens of dollars, which is similar to car wax.
The operation is not as difficult as you think. Wash the car, spray the coating agent evenly on the car paint, and then take out the matching towel to wipe and polish an area, and the whole process will be done.
Of course, there is an easier way, and that is to go to the car wash shop. After washing the car, he said, "Little brother, do me a favor, just for me."
Basically, they are very cooperative. If you give a pack of cigarettes, you will definitely help the end.
So if you want to make your car look newer, or you want to protect your car paint, you might as well try painting it yourself.
