✅ GHAD-39 · GHAD-68 (Advanced Series) only — does not fit Ace or Premium Series
What Is This?
OEM 0.35mm replacement needle — the stock size on the GHAD-39. Narrow enough for panel lines, pre-shading, and miniature work; enough flow for blending and small base coat passes. Multiple polishing stages produce an extremely smooth taper for clean, consistent paint release.
Where 0.35mm Sits
| Size | Best For |
| 0.2–0.3mm | Ultra-fine lines, extreme detail |
| 0.35mm ← you are here | Panel lines, pre-shading, miniatures |
| 0.5mm | Primers, base coats, clear coats |
Best For
✔️ Freehand panel lining — scale models, vehicles
✔️ Pre-shading and edge highlighting
✔️ Camouflage soft edges and blending
✔️ Miniature painting — NMM, skin, OSL
✔️ Weathering — streaks, chipping, dust at close range
When to Replace
⚠️ Tip blunt — spatter or uneven spray
⚠️ Bent — asymmetric pattern
⚠️ Surface scratches — intermittent paint flow
🔄 Every 50–100h, or when replacing nozzle
⚠️ Heads Up
Advanced Series only — GHAD-39 and GHAD-68.
Always replace needle and nozzle as a matched pair. A 0.35mm needle requires a 0.35mm nozzle.
