AK Interactive Sanding Sponges Flexible Foam Abrasive Pads — 6 Grits from P400 to P3000 AK9550–AK9555 | 6 Units per Pack | Foam-Backed | Conforms to Curved Surfaces ???? What Are Sanding Sponges? Rectangular foam pads with abrasive grit bonded to the surface. Unlike rigid sandpaper, the foam backing is flexible — it bends, folds, and conforms to the curves and contours of your models. This makes them dramatically more effective on miniatures and vehicles than flat sandpaper sheets, because the abrasive follows the shape of the part instead of just hitting the high spots. AK's range covers six grit grades from P400 (coarse) to P3000 (ultra-fine), giving you a complete progression from rough material removal right through to mirror-smooth polishing.
