Quick Answer

The GM06 Blue Gundam Marker is a reliable choice for panel lining on white, light gray, or yellow plastic where black lines look too harsh. Its water-based ink flows into recessed panel lines easily, and you can clean up mistakes with the GM300 Gundam Marker Eraser. For best results, let the ink dry completely before handling the part.

Why Choose Blue for Panel Lining?

Blue panel lines are a popular accent on white and light-colored Gunpla because they add depth without the stark contrast of black. The GM06 Blue marker delivers a muted navy tone that reads as a shadow rather than a hard outline. This makes it ideal for kits with a lot of white armor, like the RX-78-2 or the Strike Gundam, where you want definition without overwhelming the surface.

What You Need to Get Started

Before you begin, gather your GM06 Blue marker, a GM300 eraser, and a clean, dust-free part. If you are working on bare plastic, make sure your hands are clean or wear gloves to avoid transferring oils. For painted parts, ensure the paint is fully cured before lining. The GM300 eraser is especially useful if you are new to panel lining, as it lets you wipe away mistakes while the ink is still wet.

Step-by-Step Panel Lining with GM06

  1. Prepare the part: Clean the surface with a soft cloth or mild soapy water to remove dust and oils. Dry completely before lining. A clean surface ensures the ink flows evenly and adheres properly. Checkpoint: The part should feel smooth and show no fingerprints.
  2. Shake the marker: Shake the GM06 marker vigorously for about 10 seconds to mix the paint. This ensures consistent color and flow. Press the tip on a scrap piece of plastic until ink appears. Common mistake: Skipping this step can result in watery or patchy lines.
  3. Trace the panel lines: Gently run the marker tip along the recessed panel lines. Use light pressure and let the tip glide. Do not press hard, as this can cause the ink to pool or bleed. Checkpoint: If the line looks too thick, wipe it off with the GM300 eraser and try again with lighter pressure.
  4. Let the ink dry: Allow the ink to dry completely for at least 10-15 minutes. The paint-based formula needs time to set. Do not touch the lines during this period. Common mistake: Handling the part too soon can smudge the lines, ruining your work.
  5. Clean up mistakes: If you see any smudges or lines that went outside the panel, use the GM300 eraser to gently wipe them away while the ink is still wet. For dried ink, use a cotton swab with a little isopropyl alcohol. Checkpoint: The final lines should be crisp and confined to the recesses.
