5. Operating Instructions
Follow these steps for effective panel lining:
- Identify Panel Lines: Locate the recessed lines and depressions on your plastic model parts where you wish to apply the marker.
- Apply the Marker: Gently trace the panel lines with the ultra-fine tip of the GM01 Black marker. The ink is designed to flow into the grooves.
- Wipe Off Excess: Allow the ink to dry for a short period (typically less than 5 minutes). Then, use a cotton swab, paper towel, or even your finger to gently wipe away any excess ink that has spread outside the panel lines. The ink is formulated to be easily removable from the plastic surface.

6. Maintenance
- Cap Securely: Always replace the cap firmly after use to prevent the tip from drying out.
- Clean Tip (if needed): If the felt tip becomes clogged or accumulates dissolved paint, gently wipe it with a clean, lint-free cloth or a cotton swab dampened with a small amount of thinner (compatible with plastic models) to restore ink flow.
- Storage: Store markers horizontally at room temperature, away from direct sunlight or extreme temperatures.
7. Troubleshooting
7.1. Ink Not Flowing
- Shake and Prime: Ensure the marker has been thoroughly shaken and the tip primed by pressing it gently on scrap paper until ink flows.
- Check for Clogging: If the tip is clogged with dried ink or dissolved paint, refer to the 'Clean Tip' section under Maintenance.
7.2. Paint Dissolving on Surface
This product is primarily designed for direct application over molded plastic parts. When used over existing paint layers (such as Gundam Marker paint, Mr. Color, Gundam Color, or Aqueous Hobby Color), it may dissolve the underlying paint if it exceeds the panel line boundaries. To avoid this, apply carefully and wipe excess quickly. Consider testing on an inconspicuous area first.
