Learn how to panel line Gundam kits with this step-by-step tutorial. Master the tools, techniques, and common mistakes to achieve crisp, clean lines on any build.
Quick answer
To panel line Gundam kits cleanly, use a fine-tipped panel liner pen or a wash, apply it along recessed lines, and clean up excess with a suitable thinner. Always test on a spare part first to avoid damaging the plastic.
Choosing the Right Panel Lining Method
There are three main ways to panel line: pens, washes, and Tamiya panel line accent. Pens offer the most control for beginners, while washes flow into recesses quickly but require careful clean-up. Tamiya's accent color is a pre-mixed wash that works well but needs a gloss coat on bare plastic to prevent cracking.
Consider the plastic type: some kits use ABS plastic, which can be sensitive to solvents in washes. Always test on a hidden area first. For a safe, beginner-friendly approach, start with a fine-tipped panel liner pen.
Preparing Your Kit for Panel Lining
Before you start, make sure your kit is assembled or at least the parts are clean and free of dust. If you plan to paint, panel line after a gloss coat for best results. For bare plastic, a gentle wash with mild soap can remove mold release agents that hinder ink flow.
Gather your supplies: panel liner pen or wash, cotton swabs, and the appropriate thinner (water-based or enamel). Have a hobby knife or toothpick handy for removing dried excess.
Step-by-Step Panel Lining Process
- Test on a spare part: Before applying any liner, test on a runner or hidden part to ensure the ink flows well and doesn't damage the plastic. This is crucial if you're using a wash on bare plastic. Checkpoint: If the plastic cracks or stains, switch to a gentler method.
- Apply the liner along recessed lines: Use a fine-tipped pen or a brush dipped in wash to trace the panel lines. Let the ink flow naturally; don't press hard. For long lines, work in sections to keep the ink wet. Common mistake: pressing too hard can create blobs or scratch the plastic.
- Clean up excess while wet: Wait a few seconds, then use a cotton swab slightly damp with the appropriate thinner to wipe away excess ink. For enamel washes, use enamel thinner; for water-based, use water or isopropyl alcohol. Checkpoint: If the ink has dried, use a hobby knife to gently scrape it off.
- Seal with a topcoat: Once the panel lines are dry, apply a clear topcoat (matte or gloss) to protect the lines and decals from smudging. This also gives a uniform finish. Common mistake: skipping the topcoat can lead to lines rubbing off during handling.
