If the car paint is not dealt with in time after being scratched by other cars or the other goods, it is easy to get rusty, and the rusty part will corrode the surrounding metal slowly, what's worse, it may even rust the metal through after a long time. which means, if the car paint is peeling and gets rusty, it will cause the rust area to expand gradually, especially in rainy season, the environment is humid.
After the car paint is damaged, you could apply some toothpaste on the damaged part of the car, in order to avoid rusting. That's because toothpaste could play the role of isolation. However, the damaged part of automotive paint should be repaired as soon as possible, otherwise it may still get rusty.
If the auto paint is rusted and you want to deal with it, use sandpaper to sand off the rust first, then apply the primer. After waiting for the primer surface to dry, spray the color paint with same color as the original car paint. Surely, spraying car paint seems very simple, but it is actually a very complicated process. In fact, the whole process of dealing with rust in car paint is equivalent to refinish paint. It should be noted that the rust must be removed by the abrasive paper thoroughly, otherwise the rust may come back.
