I am very patriotic, but the domestic invisible car jacket really hurts me. What are the opinions of experienced drivers?

The first effect is definitely that the brightness of the paint surface is improved, and then it is completely isolated from the continuous damage to the paint surface by acid rain, sand, bird droppings, ultraviolet rays, etc.; it has high wear resistance to resist mild scratches , collision and prevent the car paint from being damaged by small stones splashed by the roadside when running at high speed. It has super extensibility and automatic repair function. At the same time, it isolates the contact between the car paint and the air, so that the car paint is protected.
