Treatment skills of slight scratches on cars
1. The touch-up pen can handle small scratches.
Buy a touch-up pen for coloring. Although this treatment is not as effective as going to a beauty shop, if it is a small or inconspicuous scar, it can also prevent the rust from expanding and aggravating.

When you find a new small scar on the car body, gently circle it with toothpaste and apply it to the scratch. Don't forget to apply it again after it rains or washes the car. Doing so can generally reduce scratches and imprints, and can also simply play an isolation role to prevent rust, which is no problem in the short term.

After the small scratches on the car are properly handled, the scratches should be completely repaired when the car is fully maintained next time.
