3M 401Q Magic Wet-or-dry 140x230

3M 401Q Magic Wetordry 138x230 mm – For a mirror-smooth paint finish

Want to make dust, scratches, or orange peel texture completely invisible in your paintwork? The 3M 401Q Magic Wetordry is a top-class sanding sheet, specially developed for precision work requiring a fine grit and minimal pressure. Whether you are wet-sanding an automobile body or finishing a high-quality paint layer, this sandpaper delivers results that meet the highest professional standards.

The secret lies in the combination of a water-resistant paper backing (A-grade) and razor-sharp silicon carbide mineral. This exceptionally hard material cuts very quickly and leaves an extremely consistent scratch pattern. This makes the surface much easier to polish to a high gloss after sanding. The major advantage of wet sanding with the 401Q is that you work virtually dust-free and the abrasive material does not clump together, which is essential for a smooth, flawless finish on paint, primer, gelcoat, or metal.

With the 401Q Magic Wetordry, you have control over every detail of your finish. It is the ideal choice for the professional who wants that deep, professional shine without imperfections.
