Smooth the curves. Refine the details. Perfect the finish.

The AK Interactive AK9551 Flexible Sanding Sponges are designed for controlled surface refinement and precision sanding of scale model components. Featuring a P500–600-grit abrasive surface and a flexible sponge backing, they provide an excellent balance between effective smoothing and gentle material removal, making them particularly useful for aircraft fuselages, wings, rounded components, and delicate assemblies.

Unlike rigid sanding sticks, these flexible pads adapt to the contours of your model, helping preserve natural curves while smoothing seams, removing minor imperfections, and refining previously sanded surfaces. Their high-durability abrasive material provides consistent performance, while the flexible backing makes them comfortable and easy to handle.

The sponges can also be cut to size using scissors or a hobby knife, allowing modelers to create customized sanding tools for narrow spaces, intricate details, and hard-to-reach areas.

Whether refining plastic components, smoothing resin parts, or preparing surfaces for finer sanding and primer, these versatile sanding sponges offer excellent control and precision.

Key Features

• P500–600-grit abrasive for controlled smoothing and surface refinement.

• Flexible sponge backing adapts to curved and irregular surfaces.

• High-durability abrasive material for reliable, consistent performance.

• Easy to cut and customize using scissors or a hobby knife.

• Ideal for smoothing seams, minor scratches, and surface imperfections.

• Suitable for plastic, resin, and other modeling materials.

• Pack of six sanding sponges for multiple projects and applications.

A practical addition to any modeler's workbench, because great finishes aren't just about removing imperfections. They're about knowing what to leave untouched.

Start with AK9550 (P400) for initial surface refinement, then move to AK9551 (P500–600) to smooth remaining sanding marks. Continue with AK9552 (P800–1000) and progressively finer grades for an increasingly smooth, paint-ready finish. Use light pressure around delicate raised or recessed details.
