What to Do When Rust Spots Appear on the Car Roof?

[MacJune]

If the rust is not severe, you can first use very fine water sandpaper dipped in water to gently sand off the rust spots, completely clean the area, and then apply a layer of primer. You can purchase a touch-up paint pen in advance. After the applied primer has dried, sand it smooth with water sandpaper, and then use the touch-up paint pen for color treatment. Keep a tube of ordinary toothpaste in the car. If you notice small new scratches, apply a little toothpaste. Reapply after rain or car washing.
