3M Wetordry Abrasive Sheet 401Q-02045

The 3M Wetordry Sheet 401Q 02045 provides reliable, fine-grit sanding for automotive paint prep, clear-coat finishing, and metal or primer blending. This 5½” × 9” sheet uses silicon-carbide abrasive grain that cuts quickly and evenly. Because of that, the sheet removes minor imperfections, sand nibs, or orange peel smoothly without deeper scratches.

The waterproof, A-weight paper backing makes this sheet suitable for both wet and dry sanding. As a result, you can rinse debris away, reduce dust, and avoid clogging. This keeps the abrasive surface sharp for longer during sanding sessions.

You can use the sheet on primer, paint, clear coat, gelcoat, or metal surfaces. For wet sanding of clear coats or final smoothing before polishing, the 2500-grit Wetordry delivers a smooth, refined surface ready for buffing. For primer sanding or filler blending, it offers gentle yet effective abrasion that removes ridges or filler lines without damaging the surrounding area.

Because the pack includes 50 sheets, it suits busy workshops, detail shops, or personal projects. You can tear off sheets as needed and give each job a fresh abrasive surface. This reduces waste and guarantees consistent performance across multiple tasks. Moreover, the compact size (5½ × 9 in) fits sanding blocks and hand sanding methods easily — perfect for detailed work on panels, edges, or curves.

When you sand wet, remember to keep the surface and paper slightly moist to prevent clogging and to allow a fast cut. This method also helps maintain a smooth scratch pattern that buffing and polishing can erase quickly. After sanding, the surface becomes uniform and ready for primer, basecoat, or clear coat.

Whether you’re working on paint finishing, primer prep, or metal smoothing, the 3M Wetordry Sheet 401Q 02045 offers balance between cutting speed and finesse. It helps you avoid sanding marks, speeds up prep work, and delivers consistent results — all in a versatile, easy-to-use format. Choose this Wetordry sheet when you need fine sanding performance with minimal fuss.
