What are the effects of leaving a car outside in the rain?

Leaving a car outside in the rain has the following effects: 1. The paint surface will be corroded: In China, pollution is widespread, and some areas are heavily polluted, so the rain is mostly acid rain. Therefore, rain exposes the car paint directly to acid rain, which can corrode the paint, causing rain marks, oxidation, and even cracking. 2. Dampness and mold: Compared to sunny days, the interior of the car is more prone to dampness and mold after rain. At the same time, rainwater can seep into the car body through gaps, causing metal parts to rust and corrode. Therefore, after the rain stops, accumulated moisture should be removed as soon as possible to prevent mold and other issues.
My car is often parked outside in the rain, and I've noticed that the acidity in rainwater can corrode the car's paint surface. Over time, the car becomes dull and even develops scratches and spots. When rainwater seeps into gaps, such as door edges or the chassis, metal components are prone to rust, affecting the overall lifespan of the car. Even worse, rainwater can penetrate the electronic systems, like the wiper motor or sensors, potentially causing short-circuit failures. During prolonged exposure to rain in the rainy season, the interior can become damp, with carpets developing mold and unpleasant odors, making it very uncomfortable. I recommend parking under a carport or using a waterproof car cover whenever possible, or washing and waxing the car promptly after rain to maintain its appearance and extend its service life.
As a new car buyer, I'm quite concerned about the negative effects of rain exposure. Dirty rainwater can leave unsightly stains on the car body, making the vehicle appear aged. Water accumulation in window seams or sunroof channels accelerates metal corrosion, leading to troublesome repairs. The interior becomes damp, potentially causing mold growth in the AC system that produces unpleasant odors, affecting passenger comfort. My mechanic friend advised that rainwater may also corrode small components under the hood, increasing failure risks. For daily parking, I prioritize covered spaces or shaded areas - even using a simple waterproof cover helps avoid unnecessary maintenance costs and preserves my peace of mind.
