Is car paint treated in the paint booth afraid of sun exposure?
First of all, we have to understand how the paint booth services the car. The car is sprayed inside the paint booth and then baked. The typical baking temperature is close to 200 degrees Celsius.
So, will exposure to the sun affect the automotive paint?
The temperature of sun exposure is far lower than the baking temperature, so the automotive paint is not afraid of the heat at all. However, it is affected by the ultraviolet radiation carried by the sun, which can cause long-term corrosion. Exposure to the sun's ultraviolet radiation will certainly accelerate the aging of the paint. This mainly depends on the length of exposure time.
The quality of the car's original paint does not have much effect on its resistance to UV exposure. Generally, problems may exist in the following situations:
• The original paint of the car is damaged, and the quality of the repainted finish is not as good as the original paint, making it more likely to be affected by exposure.
• Wiper arms, the edges under windows, and other complex, small parts—details that are usually given less attention—have paint strength and stability that cannot be compared to the overall body strength, and they are therefore more easily affected by sun exposure. 
Overall, with current automotive painting technology, sun exposure does not have too much impact in the short term, so you don't need to worry too much. However, some of the smaller details of the car really do need more attention.
