Panel lining is one of the most rewarding steps in model kit building. It brings out the details of your kit, making it look more realistic and polished. But when it comes to dark plastic, many builders face a common problem: black panel liners simply disappear into the dark surface. That's where the GM03 Brown Liner Gundam Marker comes in. In this guide, we'll show you how to use this brown liner effectively on dark-colored parts, step by step.

Whether you're working on a Gunpla kit with navy blue armor or a dark gray mecha, the brown liner provides a subtle yet visible contrast that enhances the panel lines without looking too harsh. Unlike black, brown adds warmth and depth, making it perfect for dark plastics. Let's dive into the techniques that will elevate your panel lining game.

Why Choose Brown for Dark Plastic?

When you panel line dark plastic with black, the lines often get lost or look too stark. Brown, on the other hand, offers a softer contrast that still defines the panel lines clearly. The GM03 Brown Liner is specifically designed for this purpose, with a fine tip that allows precise application even in tight recesses.

Additionally, brown has a slightly warm tone that complements the cool tones often found in dark plastics, such as navy, charcoal, or deep gray. This creates a more natural shadow effect, as if the light is hitting the panel lines at an angle. For beginners, using a brown liner on dark kits is a game-changer, as it reduces the need for multiple coats and touch-ups.

  • Brown provides a visible contrast without being overpowering.
  • The fine tip of the GM03 liner allows for precise application.
  • Warm brown tones complement cool dark plastic colors.

Tools You'll Need

Before you start, gather the essential tools. You'll need the GM03 Brown Liner Gundam Marker, a cotton swab or eraser, and some isopropyl alcohol or a dedicated panel line cleaner. Having a hobby knife or toothpick can also help with cleaning up mistakes.

If you're working on a kit with intricate details, consider using a masking tape to protect areas you don't want to line. For example, the AK8203 Masking Tape 5MM is perfect for this purpose, as it can be cut to size and applied precisely. This ensures clean lines and prevents accidental smudging.

Step-by-Step Panel Lining Process

Start by ensuring your kit is clean and free of dust. If you're panel lining on bare plastic, you can proceed directly. If you've painted your kit, make sure the paint is fully cured. Begin by shaking the GM03 Brown Liner well, then press the tip gently on a piece of paper to get the ink flowing.

Next, carefully draw the liner along the panel lines, letting the ink flow naturally. The fine tip allows you to follow the recesses without going over the edges. For longer lines, you can draw in one fluid motion. Once you've applied the liner, wait a few seconds for the ink to dry slightly.

After the ink has dried, use a cotton swab or your finger to gently wipe away any excess ink that has bled onto the surface. The key is to do this while the ink is still slightly wet, so it doesn't stain the plastic. If you make a mistake, use a small amount of alcohol on a cotton swab to clean it up.

  • Shake the marker well before use.
  • Apply the liner along the recesses, letting the ink flow naturally.
  • Wipe excess ink with a cotton swab while still wet.
  • Use alcohol for clean-up if needed.

Tips for Dark Plastic Kits

When working with dark plastic, you might find that the brown liner doesn't show up as prominently as you'd like. In that case, you can apply a second coat after the first one dries. This will darken the line and make it more visible.

Another tip is to use the liner on parts that have deep panel lines, as they will hold the ink better. For shallow lines, you might need to go over them twice. Additionally, consider using a topcoat after panel lining to protect the lines and give your kit a finished look. The AK11237 Gen-3 Matt Varnish 100 ml is an excellent choice for a matte finish that will make the panel lines stand out subtly.
