Mr.Hobby GSI-MT301 Sandpaper Pack 400/600/1000 Grit 2 Sheets Each  [GSI-MT301]

All-Round Sanding for Model Builders

The Mr.Hobby GSI-MT301 waterproof sand paper set is a handy kit for fine surface work on scale models and RC parts. It contains two sheets each of 400, 600 and 1000 grit so you can move from rough shaping to fine finishing with confidence.

Everyday Uses in RC Work

From trimming seams on plastic bodies to flattening primer on resin parts, this set gives you the grits needed for common garage tasks. The waterproof backing also makes wet sanding practical when you need to reduce dust and see the surface progress more clearly.

How to Sequence the Grits

Start with the 400 grit for heavier material removal, switch to 600 for smoothing, and finish with 1000 for a refined surface ready for paint or decal work. Using a flat block helps keep edges true and prevents over-sanding thin areas.
