Will the car chassis rust when driving in rainy days?

Driving in rainy days will not cause the car chassis to rust, as the chassis has been treated with anti-rust measures during the original factory production. Here are some tips to prevent car rust: 1. Be vigilant about minor scratches: Rust often appears on the car paint surface. Besides common collisions and scratches, small stones kicked up by tires can also cause tiny paint chips, which may develop into small rust spots over time. These minor damages are often overlooked as they usually occur in inconspicuous areas. 2. Regularly check moisture in areas prone to water accumulation: It's inevitable to encounter rain, snow, or muddy roads while driving. Sludge can accumulate in gaps under the car body and on the floor inside the car. If not cleaned promptly, moisture can hide in these areas. 3. Apply glaze sealing for soft paint surfaces: For vehicles with softer paint, wind-blown sand particles during high-speed driving can cause fine scratches. Applying glaze sealing can create a strong, mesh-like protective film, enhancing the paint's hardness, with effects lasting about a year. Coating can also achieve similar results. 4. Avoid using car covers when parked outdoors: In windy and rainy weather, the inner layer of a car cover may repeatedly flap against the car paint, especially if sand gets inside the cover, leading to countless fine scratches on the car body. Over time, this can cause the paint to lose its luster.
To be honest, having driven for over a decade, I can confirm that chassis rust is absolutely related to rainy weather. Think about it – rainwater mixed with road grime gets splashed directly onto the undercarriage, and those crevices and corners are particularly prone to pooling water. If the drainage holes get clogged, or the factory-applied protective coating on the chassis gets scraped off, exposing the bare metal to sit in dirty water, rust spots will inevitably appear over time. This is especially critical for older cars – my neighbor spent over 5,000 yuan repairing his rusted-through chassis. That's why after every rainy season, I make it a point to visit a car wash for an undercarriage rinse and thoroughly check all those nooks and crannies for trapped water. At least this way, I can drive with peace of mind.
