Rain can have certain effects on a new car. It is best to avoid exposing a new car to rain, as rainwater contains many acidic substances and invisible particles that can corrode the protective film on the car's paint surface, while oxidation of these particles can also damage the car body. It is important to rinse the car promptly after rain. In heavily polluted areas, the air contains a lot of sulfur dioxide, nitrogen oxides, and dust particles, which rise into the clouds and condense into acid rain that falls on the car body. If not washed after prolonged exposure to rain, the car's paint can be damaged. Hazards after rain exposure: Compared to sunny weather, the interior of the car is more prone to moisture and mold after rain. At the same time, rainwater can seep into the car body through seams, affecting metal components and making them prone to rust and corrosion. Therefore, it is necessary to remove accumulated moisture as soon as possible after the rain stops to prevent mold and other issues. Solutions after exposure to acid rain: Rainwater, especially acid rain, can still cause some damage to the car's paint. The best solution is to apply paint sealant, coating, or crystal coating to the car, as these treatments can effectively protect the paint. Regularly rinsing the car body or waxing it after rain exposure, and parking the car in a sheltered place whenever possible, are good practices. If parking outdoors, it is best to cover the car with a car cover, which can both waterproof and keep the car body clean.
