Foam Sponge Sandpaper, 8 Grits #400–#2500, Flexible 80x20mm Pads (DSP-400/600/800/1000/1200/1500/2000/2500)

A soft foam backing changes how sandpaper works: each 80 x 20 mm sheet bends to follow curved armor, rounded canopies, and cylindrical parts, keeping full abrasive contact where flat paper only touches the peaks. It evens pressure out, so curves sand smooth instead of faceted.

The durable sponge core cushions your fingers too, spreading force evenly for consistent strokes and comfortable long sessions, and it conforms gently to contours that would otherwise need a shaped stick, holding its abrasive firmly through session after session.

Eight grits from aggressive #400 shaping up to ultra-fine #2500 cover the whole ladder: leveling seams, refining primer, finishing topcoat, and polishing to a mirror sheen on plastic models, resin casts, and 3D prints alike.

FAQ

1. Question: What advantage does the sponge backing have over regular flat sandpaper?

Answer: Flexibility and even pressure. The foam layer lets each 80 x 20 mm sheet bend around curved surfaces—dome canopies, cylindrical thrusters, rounded armor edges—so the abrasive stays in full contact instead of only touching the high spots. The cushioning also spreads your finger force evenly, which means fewer flat spots, no faceted curves.

2. Question: Which materials does it work on?

Answer: It sands plastic model parts (PS, ABS), resin casts and 3D prints, primed and painted surfaces, and soft woods—the same range as standard hobby sandpaper, with the added benefit of conforming to shapes. As with any abrasive, avoid hardened metal: grinding metal will clog and destroy the grit and can damage the part you are working on.
