3M 02601 – Softback Sanding Sponge Ultrafine (4½ in × 5½ in, 20 Pcs)

3M 02601 Softback Sanding Sponge Ultrafine (4½ in × 5½ in) is a professional-grade sanding sponge designed for ultra-smooth surface finishing and fine detail work in automotive refinishing, woodworking, and general surface preparation applications. With an ultrafine abrasive surface on a soft, conformable backing, this sanding sponge delivers gentle, precision sanding that helps create a flawless finish before painting, polishing, or clearcoating.

The ultrafine grit makes it ideal for final sanding, between-coat smoothing, blending surface imperfections, and preparing a surface for finishing steps where a very smooth feel and minimal scratch pattern are critical. Its softback construction conforms to contours and curves for consistent contact, reducing the risk of gouges and uneven sanding marks during hand sanding.
