How many degrees does the weather affect the car paint?

Temperatures above 40 degrees will affect the paint. Type of paint: ordinary paint: ordinary paint is the most common paint in automobiles, which is characterized by low cost and simple technology, but its gloss is not very good, its surface hardness is not high, and it is particularly easy to scratch. So it is rarely used in cars, even if there are low-profile models, it is mostly used in trucks and buses. Metallic paint: Metallic paint is made of aluminum powder on the basis of ordinary paint, so it looks very bright when finished. The biggest feature of metallic paint is not only its high brightness, but also its hardness is much higher than that of ordinary paint. Ordinary objects are not easy to scrape off, so cars, especially high-end cars, are basically painted with metal. Pearlescent paint: Pearlescent paint uses mica instead of aluminum particles. Mica pigment coated with titanium dioxide and iron oxide is added to its paint base. After the light hits the mica particles, the colors of titanium dioxide and iron oxide first appear, and then complex refraction and interference occur in the mica particles.
