Are Cars More Afraid of Sun Exposure or Rain?

[LeTucker]

Cars are most vulnerable when exposed to sunlight after being rained on without drying. The reasons are as follows: 1. Reason: Raindrops adhering to the car body act like small magnifying glasses. When sunlight hits the car's paint surface under these 'magnifying glasses,' it can scorch the paint. Prolonged exposure to sunlight can also cause the paint to lose its luster. 2. Daily Maintenance: Since rainwater is acidic, failing to wash the car after rain can lead to paint erosion. Moreover, with declining air quality, rainwater now contains many impurities. Therefore, car owners should wash their cars again after exposure to rain.
