How to touch up car paint?

[LeilaniRose]

Car paint touch-up methods are: 1. Completely remove rust, dirt, and grease from the paint surface. You can use ultra-fine water sandpaper dipped in water to gently sand away rust spots; 2. Carefully use tape to demarcate the area above and below the scratch; 3. Shake the touch-up pen vigorously more than 30 times to ensure the paint is evenly mixed; 4. After waiting for 3 days, remove the tape and observe the paint surface. Carefully inspect the damaged area of the car. If the damage exceeds one-third of the component, a transitional repair method should be used. Transitional repair involves applying clear coat to the entire component and blending the color coat from the damaged area to the original paint, which maximizes the retention of the original car paint and avoids color mismatch issues.
