Waterproof Abrasives for Precise Model Prep

For neat seams and smooth panels on scale builds, dependable abrasives are essential. Mr. Hobby GSI-MT303 Waterproof Sandpaper #180 - 4 Pieces provides four waterproof sheets intended for controlled wet or dry sanding to aid in achieving a clean substrate for paint or filler.

Appropriate Grit for Rough Shaping

The #180 grade is useful for removing flash, levelling joints and shaping parts prior to finer finishing. It is effective on plastics, resins and light metal pieces without excessively damaging small details when used with care.

Wet Sanding to Minimise Clogging

Because the paper is waterproof, you can sand with water to limit dust and help keep the abrasive cutting. This assists in maintaining a consistent finish and reduces the need to replace clogged sheets frequently.

Will this grit remove mold lines effectively?

Yes. #180 is commonly used to remove mould lines and flatten small imperfections before stepping up to finer abrasives.

Can I use these sheets straight on a block?

They work well on a flat sanding block for large surfaces; use a shaped block or hand-wrap for curves and contours.

How should I store unused sheets?

Keep them flat and dry to preserve the waterproof coating and avoid creasing that could affect performance.

Are there tips for finishing after #180?

Progress through finer grits after #180 and finish with a polishing compound or micro-mesh for a smooth painted surface.

Is wet sanding better than dry for paint prep?

Wet sanding tends to produce a cleaner surface with less dust and reduced clogging, making it preferable for final prep before primer or paint.
