AK Modelling Tool
Sponge P400 Grit (6 Units) (AK9550)
The AK P400 Grit Sponge set includes six high-durability flexible sanding sponges designed for controlled surface preparation, smoothing, and polishing. Each sponge can be bent to follow curves and contours, making them especially useful on rounded parts, fuselages, hulls, and complex shapes where rigid sanding sticks struggle.
The sponges can also be easily cut with scissors or a knife to create custom sizes for tight spaces and detailed work. With a P400 grit rating, they’re ideal for general sanding tasks such as refining seams, preparing surfaces for paint, and blending filler, offering a good balance between material removal and finish quality.

This is one of those basics you end up reaching for constantly. Great for knocking back seams, smoothing filler, or just giving parts a quick once-over before paint. Simple, practical, and surprisingly versatile once they’re sitting on your bench.
If there are more grits coming next, send them over. These sponge sets work best as a small progression rather than on their own.
