What is the method for car touch-up painting?

[ClaireLee]

Car touch-up painting method is: 1. Clean the scratched area thoroughly, prepare a touch-up paint kit, soak the sandpaper in water and wrap it around a hard cotton block; 2. Use the wrapped sandpaper to smooth the scratched area until you can't feel any unevenness compared to the surrounding paint surface by hand; 3. Use tape and cloth to cover areas that don't need touch-up painting; 4. Prepare the touch-up pen and spray can, assemble them together, and start spraying paint from a certain distance from the scratch, moving back and forth until the color covers the black area; 5. After the paint dries, prepare blending clear coat, which helps make the touched-up paint color closer to the car's original color and protects the repaired paint; 6. Assemble the blending clear coat on the spray can, spray it back and forth over the touched-up area from a certain distance, wait for a while, and the touch-up painting is completed.
