Precision Finishing with Mr.Hobby GSI-MT304

Scale model makers looking for a dependable mid-grit option will find the Mr.Hobby GSI-MT304 #400 useful for surface prep. The four sheets in the pack are handy for smoothing and shaping parts ahead of primer and paint.

Applications for Scale and Scratchbuilt Work

These waterproof sheets are good for tidying joins, knocking back flash and refining small details prior to finishing. Their construction suits controlled wet sanding on delicate plastics and denser resins.

Grit Choice for Mid-Stage Sanding

The #400 grit sits between heavy shaping and fine polishing, so it removes minor blemishes without aggressive cutting. That balance makes the sheets practical for a wide range of kit tasks.

How do I wet sand without overdoing it?

Use light pressure and slow strokes, keep the surface lubricated, and frequently check progress to avoid removing too much material.

Can I use these sheets on primer?

Yes, they are suitable for smoothing cured primer coats before final prep, but start gently to prevent cutting through thin layers.

Is it okay to trim the sheets for detail work?

Absolutely, you can cut the sheets to fit small blocks or touch-up sticks to reach tight areas and edges.

How many passes will one sheet typically last?

Lifespan varies by pressure and material, but one sheet will normally handle several small parts or multiple light passes on larger components.
