How long after car painting can it be exposed to water?

[Annie]

1 day or so is generally sufficient before the car can be exposed to water. The front and rear ends of the car are equipped with bumpers, which not only serve a decorative function but, more importantly, act as safety devices that absorb and mitigate external impacts, protecting the vehicle body and ensuring the safety of passengers. These plastic bumpers are typically made from two types of materials: polyester-based and polypropylene-based, and are manufactured using injection molding. Below is some relevant knowledge about bumpers: Bumpers are devices designed to absorb and cushion external impacts when the vehicle or driver is subjected to force, providing protection for both the occupants and the vehicle. In addition to maintaining their original protective function, modern front and rear bumpers also aim to harmonize with the vehicle's overall design and pursue lightweight construction.
