Mr. Hobby GSI-MT303 Waterproof Sandpaper #180 - 4 Pieces Model Finishing Sheets  [GSI-MT303]

Waterproof Sheets for Accurate Surface Prep

For tidy panel lines and smooth paint bases on scale models, choose abrasives that hold up. Mr. Hobby GSI-MT303 Waterproof Sandpaper #180 - 4 Pieces provides four durable sheets meant for wet or dry sanding so you can control the finish without frequent replacement.

Right Grit for Rough Shaping

The #180 grade is suited to the earliest smoothing stages, removing mold lines and shaping parts. It performs well on plastics, resin castings and basic metal components while preserving fine features.

Wet Sanding Benefits for Cleaner Results

Using these waterproof sheets with water reduces airborne dust and helps the paper resist clogging. That means more consistent abrasion and a cleaner path to final polishing or priming.
