Step-by-Step Painting Process
Step 1: Inspect & Light-Sand
Even though parts arrive pre-sanded, do a quick inspection under good lighting. Sand any rough areas with 400-grit paper using circular motions. A pre-primed surface is your starting point — a final light pass ensures paint lays perfectly flat.
Step 2: Disassemble Using the Magnet System
Remove arms and head at the magnet connection points. The magnet system was designed with this zone-based painting workflow in mind — painting separate pieces is far easier than working on an assembled figure.
Step 3: Apply Base Coats
Apply color in thin layers — the goal is even coverage, not single thick coats. Thin your paint ~30% for brushwork, 1:1 for airbrush. Allow each coat to fully dry before the next (20–30 min for acrylics).
Tip for white areas: Apply a light gray base coat first. White over gray covers more evenly and requires fewer passes.
Step 4: Mask for Color Separation
Apply fine masking tape along color borders after the base coat is fully dry. Burnish tape edges firmly. Apply second color, remove tape while paint is slightly tacky. The fat chibi's bold color blocks make masking simpler than detail-heavy kits.
Step 5: Panel Lining & Small Details
Apply a thin enamel wash (dark brown or black) over the figure. Let dry 15–20 min, then wipe back with enamel thinner on a cotton swab, leaving color only in panel recesses. This creates depth and definition.
For the Zaku II mono-eye: a dot of pink/magenta followed by a tiny gloss coat creates a convincing "lit" sensor effect.
Step 6: Topcoat & Reassembly
Apply a gloss coat before enamel washes (makes cleanup easier), then seal with a final matte topcoat once all work is complete. Allow 24 hours before reassembly via magnet connections.
Note: Keep magnet connection points clear of paint buildup — mask them during painting for clean contact.
Frequently Asked Questions
Q: How long does the whole painting process take?
For a beginner, expect 4–8 hours spread across multiple sessions. The most important rule: don't rush drying time between coats. Patience at each stage produces significantly better results.
Q: Can I paint directly on the pre-primed surface?
Yes, though a light 400-grit touch-up pass is still recommended for the smoothest final result. The pre-primed surface gives you a solid foundation — you're just refining it.
Q: What if paint gets into the magnet connection points?
Mask connection areas with blu-tack or small tape pieces while painting. Avoid building up thick paint layers at the joints — this can prevent clean magnetic connection after reassembly.
Q: My enamel wash looks too dark — how do I fix it?
Enamel washes remain workable for several hours after application. Use enamel thinner on a cotton swab and wipe back more aggressively. Work in small areas and build up gradually.
Q: Can I mix acrylic and lacquer paints on the same kit?
Yes — but observe the correct layering order. Lacquers go down first; acrylics go on top. Never apply lacquer over acrylic — lacquer solvents will dissolve the acrylic beneath it.
