What are the pros and cons of nano-coating agents for car paint?

[Mockingjay]

Nano-coating agents offer the following benefits for car paint: 1. After coating, the paint is isolated from contact with air, preventing oxidation and avoiding phenomena such as white cars turning yellow or black cars becoming dull within the effective period; 2. The car surface becomes less prone to dust accumulation, making it easier to clean, which is known as the self-cleaning property of the coating. It enhances the glossiness of the paint surface, making the car appear shinier. After coating, especially when using Nissan Amica coating, the hardness of the paint surface increases, effectively preventing or reducing minor scratches. Before applying the coating to a new car, a slow-speed soft paint restoration pad should be used to remove the oxidation layer from the paint surface without the need for polishing, which in itself is a form of protection for the car paint.
