Is it necessary to repair scratched underbody paint?

[DeEliana]

It is necessary to repair scratched underbody paint; otherwise, the aging speed of the underbody will significantly increase. Underbody paint (underbody armor) is a non-toxic, sticky rubber coating that forms a strong, elastic protective layer after spraying and drying. Below is some relevant information about underbody armor: The functions of underbody armor: It provides protection against collisions, rust, and the impact of flying stones and gravel. Even when temperatures exceed 148 degrees, it will not flow or sag. It can also withstand the heat from the road surface in summer, the erosion of acid rain, and prevent gravel on the road from hitting and damaging the original rust-proof paint and zinc coating on the underbody. Areas that do not require underbody armor: The following areas do not need underbody armor, such as the engine compartment, exhaust pipes, fuel lines, heat insulation layers, and joints. These areas should be covered with newspaper during application.
