Setup and Preparation
Proper preparation is crucial for a successful repair. Follow these steps before applying the touch-up paint:
- Verify Color Code: Ensure you have the correct paint code for your vehicle. This product is specifically for VW Deep Black Pearl (LC9X/2T). Your vehicle's paint code can typically be found on a sticker in the door jamb, under the hood, or in the trunk.
- Clean the Area: Thoroughly clean the damaged area and the surrounding surface with soap and water, then dry completely. Remove any wax, grease, or rust.
- Remove Loose Paint: Gently remove any loose or flaking paint from the chip or scratch using a fine-grit sandpaper or a soft abrasive pad. Clean the area again.
- Masking (Optional): For larger scratches or to protect surrounding areas, use masking tape to create a clean border around the repair area.
- Shake the Pen: Shake the touch-up paint pen vigorously for at least 30 seconds to ensure the paint is thoroughly mixed. You should hear the mixing ball inside.
- Test Application: Before applying to your vehicle, test the paint on an inconspicuous area or a piece of scrap material to confirm color match and application technique.

Operating Instructions
Follow these steps for effective application of the BIOOICH Touch Up Paint Pen:
- Prepare the Surface: Ensure the area is clean, dry, and free of loose debris as per the setup instructions.
- Shake the Pen: Shake the pen well for 30 seconds immediately before each application to ensure consistent color.
- Apply Thin Coats: Press the pen tip gently onto the scratch or chip. Apply the paint in thin, even coats, moving in one direction. Avoid applying too much paint at once, as this can lead to uneven drying and a raised appearance.
- Allow Drying Time: Allow each coat to dry for 10-15 minutes before applying the next. Multiple thin coats are better than one thick coat for a smooth finish and better adhesion.
- Build Up Layers: Continue applying thin layers until the scratch or chip is filled and the paint is level with the surrounding surface.
- Final Drying: Allow the final coat to dry completely for at least 24 hours before exposing to moisture or polishing.

Maintenance
To ensure the longevity and effectiveness of your BIOOICH Touch Up Paint Pen:
- Clean the Tip: After each use, wipe the pen tip with a clean cloth or tissue to remove any excess paint. This prevents clogging and ensures smooth application for future use.
- Secure the Cap: Always replace the cap tightly after use to prevent the paint from drying out.
- Storage: Store the pen in a cool, dry place, away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Color Mismatch | Incorrect paint code selected; paint not thoroughly mixed. | Double-check your vehicle's paint code. Shake the pen vigorously for at least 30 seconds. Test on an inconspicuous area before applying to the main repair. |
| Paint Not Flowing | Pen tip clogged; paint dried out; insufficient shaking. | Clean the pen tip. Ensure the cap was tightly sealed during storage. Shake the pen thoroughly. |
| Uneven Application / Raised Paint | Too much paint applied in one coat; insufficient drying time between coats. | Apply paint in very thin, even layers. Allow each coat to dry completely (10-15 minutes) before applying the next. Lightly sand down raised areas if necessary before applying subsequent coats. |
| Paint Chipping Easily | Improper surface preparation; insufficient drying time; paint applied too thickly. | Ensure the surface is thoroughly cleaned and free of loose paint/rust before application. Apply multiple thin coats instead of one thick coat. Allow the final coat to cure for at least 24 hours. |
