What are the methods to deal with rust spots on car paint?

[BethanyDella]

After wiping off the rust spots, you can use a fine needle or toothpick to apply matching paint, or use a touch-up pen. It is recommended to go to a 4S shop for touch-up and polishing treatment. Polishing: The coarseness of the polishing wax used depends on the degree of oxidation of the car paint. If the particles of the sand wax are relatively coarse, it is suitable for grinding off deeper scratches, but it causes greater damage to the car paint. Although polishing has a relatively obvious effect, it should not be used frequently. Frequent polishing of the car will thin the car paint, directly affecting the service life of the car paint surface. Touch-up pen: Although the touch-up pen cannot remove the rust spots on the car paint, it can cover the rust spots to some extent. It can be said to treat the symptoms but not the root cause. It can be used for emergencies, but it is also necessary to clean the vehicle in time to prevent rust spots on the car paint surface.
