Can a car be exposed to rain after being painted?

[LePatrick]

A car should not be exposed to rain after being painted. It is safer to avoid washing the car or getting it wet for two days. Generally, if the painting is done at a 4S shop, the car will undergo processes like baking the paint, and it usually takes two to three days before the car can be picked up. The car paint is quite complex, consisting of four layers from the inside out: the electrophoretic layer, the primer layer, the color layer, and the clear coat. The electrophoretic layer primarily serves as an anti-rust measure. After the entire car body is assembled, it is immersed in an electrophoretic bath, forming this layer on the surface. Above the electrophoretic layer is the primer layer, which also prevents rust and enhances adhesion to the next layer of paint. The color layer, above the primer, mainly provides the aesthetic appearance. The outermost layer is the clear coat, which protects the color layer and enhances the glossiness of the car's paint.
