What is the maximum temperature that car paint can withstand?

Car paint can withstand a maximum temperature of 60°C. Below are specific details on car paint maintenance: 1. Waxing: Waxing forms a protective wax layer on the car's surface, isolating the paint from external elements, thus protecting it from oxidation and fading. New cars do not require waxing within the first 3 months of purchase, and excessive waxing afterward can damage the paint—limit waxing to once every two months at most. When waxing, apply evenly and maintain a consistent direction. 2. Timely cleaning: After driving in the rain, wash the car promptly once the weather clears to prevent acid rain corrosion. 3. Crystal coating: Crystal coating creates a robust fiber network on the paint surface, filling microscopic pores invisible to the naked eye, achieving a mirror-like effect. It adds a thin diamond-hard shell to the paint, further enhancing the hardness beyond traditional coating and protecting the paint from damage.
I often drive in high-temperature areas and notice that car paint is particularly prone to issues under intense sunlight. Even car washes avoid using hot steam guns directly on the paint, fearing the high temperature might damage the clear coat. Generally, car paint is designed to withstand temperatures between 80 to 120 degrees Celsius, depending on the manufacturing quality, with imported paints possibly tolerating higher temperatures. Under direct summer sunlight, the car's surface temperature can soar to over 70 degrees, and with added engine heat, areas near metal components get even hotter. If your car is parked near industrial zones or steel plants, the temperature conditions are even harsher. I recommend parking in shaded areas whenever possible, as prolonged exposure to high temperatures can not only cause fading but also make the paint brittle and prone to cracking.
Car paint is actually quite delicate, and high temperatures can significantly affect it. The original factory baking paint process can typically withstand around 100 degrees Celsius, but real-world driving conditions are far from ideal. I've seen many car owners park their vehicles on asphalt roads under direct sunlight, where the paint temperature exceeds 80 degrees, accelerating aging. Car paint mainly consists of a primer and a clear coat layer, with the clear coat being the most vulnerable to heat—excessive temperatures can cause bubbling and cracking. For modified cars, extra caution is needed, as wraps and vinyl films tend to lose adhesion under high heat. If you frequently drive in hot climates, consider applying a ceramic coating, which can slightly improve heat resistance. Never pour cold water on hot car paint, as extreme temperature differences can easily cause cracking.
