How to Touch Up Paint on a Car?

[LeKeira]

To touch up paint on a car, follow these steps: 1. Clean the scratch, completely removing any rust from the paint surface. Start by using very fine water sandpaper dipped in water to gently sand away the rust spots, then thoroughly wipe it clean to ensure the rust does not spread; 2. Repair the paint surface, carefully using tape to mask off the area above and below the scratch. Then, take a touch-up paint pen and apply it evenly over the scratch. Apply a thin layer first, wait for the paint to dry slightly, then proceed with a second and third coat until the painted area is slightly raised above the surrounding normal paint; 3. Sand and polish the paint. After waiting for 3 days, remove the tape and use a single-edge razor blade to gently scrape off any excess paint. Then, touch up the paint again and wait another 2 days. Soak 2000-grit waterproof sandpaper in soapy water for 20 to 30 minutes, secure the sandpaper with a sanding block, and gently sand the painted area with water until the paint surface is level with the surrounding area.
