Mr.Hobby GSI-GT20 Sand Paper Set 180/240/320 grit, 6 pcs  [GSI-GT20]

Sand paper for RC model finishing

The Mr.Hobby GSI-GT20 sand paper set provides three common grits—180, 240 and 320—in a compact six pcs pack for RC scale model surface work. These sheets are intended for manual sanding tasks such as trimming excess material, evening out filler, and preparing surfaces before primer and paint.

Work progressively from the coarser 180 grit to the finer 320 grit to remove tooling marks and refine edges; use light, controlled strokes and inspect frequently on small components like body panels, bumpers, or detail parts. The sheets are sized for hand use and are compatible with small sanding blocks if you prefer a flat surface for larger panels.

Keep separate sheets for putty sanding and for final paint prep to avoid cross-contamination. When working on thin plastics or delicate details, start with minimal pressure and consider backing the sheet with a thin block to avoid over-sanding edges.
