How long should a car avoid rain after crystal coating?

After crystal coating, the car should avoid rain for 24 hours, refrain from wiping the paint surface for three days, and avoid washing for one week. Below is more information about car crystal coating: Reason: Since car film is mainly applied to the interior side of the car windows, rain won't affect it as long as the windows remain closed. Function: The primary functions include blocking UV rays, reducing heat, preventing injuries from shattered glass, reducing glare, and protecting personal privacy due to the one-way visibility of the film. Additionally, it minimizes damage to interior items and passengers from UV exposure, lowers the car's interior temperature through physical reflection, reduces the need for air conditioning, thereby saving fuel and expenses. Working Principle: The film is created using vacuum deposition or magnetron sputtering technology to form multiple layers of highly insulating metal coatings from materials like aluminum, gold, copper, and silver. The outer shell electrons (free electrons) in these metals are not tightly bound to the nucleus. When exposed to light waves, the electric field of the light causes these free electrons to absorb energy and oscillate at the same frequency as the light, subsequently emitting light of the same frequency, which is known as light reflection.
