If you want your model kits to look like the professional builds on Instagram, Gunpla panel lining is the single most important skill to master. Without it, your kit looks like a plastic toy; with it, it looks like a 60-foot mechanical war machine.
In this lesson of our Gunpla 101 series, I’m breaking down the three major methods to add detail, using our HG Demi Trainer as the canvas.
1. The Easiest Entry: Gunpla Panel Lining with Markers
For beginners, using a Gundam Marker is the safest and fastest way to start.
- Why it works: These are fine-tip permanent markers that fit perfectly into the molded grooves of your kit.
- The DK Hobby Hack: If you make a mistake, don’t panic. A simple cotton swab dipped in 70% isopropyl alcohol will erase any smudge instantly.
2. The Cleanest Lines: Tamiya Panel Line Accent Color
If you want ultra-thin, sharp lines that look like real machine gaps, you need an enamel-based wash.
- The Technique: Simply touch the brush to a corner and watch the ink “flow” through the lines via capillary action.
- Safety First: Enamel can be harsh on plastic! Always work in a ventilated area and avoid letting the ink pool in moving joints to prevent the plastic from cracking.
3. Advanced Customization: Gunpla Scribing for Beginners
Sometimes the molded lines on a High Grade (HG) kit are too shallow, or you want to add your own custom designs. This is where Gunpla scribing comes in.
The Best Scribing Tools for Beginners
To start scribing without ruining your kit, I recommend:
- Chisels: A 0.125mm or 0.15mm chisel is the standard for 1/144 scale kits.
- Scribing Tape: Never freehand! Use specialized hard tape (like Dymo or guide tape) to act as a “ruler” for your blade.
Pro Tips for a Perfect Scribe:
- Zero Pressure: Let the weight of the tool do the work. Drag it lightly 10 times rather than pushing down once.
- Rotate the Part, Not the Tool: When scribing a corner, keep your hand steady and move the plastic piece instead.
- The Symmetry Hack: Use a compass or a toothpick to measure the distance from the edge on both legs so they match perfectly.
