The Story
When there's real material to remove — chunky mould lines, sprue nubs, heavy seams — you start coarse. Tamiya's 400-grit sanding sponge sheet does the shaping work, its flexible foam base moulding to curves and corners a rigid block would skip straight over. Cut it to size and sand wet or dry on plastic, wood and metal.
At a glance
- Grit: 400 (coarse)
- Dimensions: 114 x 140mm
- Abrasive: aluminium oxide; sponge thickness 5mm
- Suitable for wet sanding; cut to size with a knife
Why it's good

- The coarse first step in a full sanding routine
Get the shaping done here, then work up through the finer grits.
Where the heavy lifting happens. Move on to the 600 and 1500 sheets as the surface comes good.
