Is it necessary to repair scratches on the car's underbody paint?

[OTimothy]

Underbody paint needs to be repaired. In this case, repainting is necessary; otherwise, the aging speed of the underbody will significantly increase. It is a non-toxic, sticky rubber coating that forms a strong, elastic protective layer after spraying and drying. The following are the functions of underbody coating: 1. It can prevent collisions, rust, and the impact of flying stones and gravel. Even when the temperature exceeds 148°C, it will not flow or sag; 2. It can also resist the baking heat from the road surface in summer, the invasion of acid rain, and prevent gravel on the road from hitting the underbody and damaging the original rust-proof paint and zinc layer.
