3M Wetordry 401Q Paper Sheet for Wet

3M™ Wetordry™ Abrasive Sheet 401Q is designed for sanding applications that require a fine grit and a light touch, such as auto body wet sanding and paint finishing. It combines a durable, waterproof A-weight paper backing and 3M's fast-cutting silicon carbide mineral for consistent scratch patterns, making for easier buffing. And a range of grades up to 3000 grit allows for superior results.

3M™ Wetordry™ Abrasive Sheet 401Q  is ideal for leveling minor dust nibs, adjusting mismatched orange peel, light sanding on acrylic lacquer paint and other sanding jobs where burning or sanding through clear coat and paint are primary concerns, the 3M™ Wetordry™ Abrasive Sheet 401Q makes excellent results easier: it’s durable yet flexible, with a sharp cut that leaves a refined finish. The durable paper backing helps create consistent patterns that are easily buffed out. And the silicon carbide grain is available in grades from 1000 up to 3000 for a full range of non-aggressive sanding and polishing jobs on clear coat, plastic and metal, including areas that require hand compounding and for sanding dark colored paints. 

The 3M™ Wetordry™ products are backed with a durable waterproof paper backing that supports wet and dry applications. Lighter weight than cloth and smooth rather than textured, the paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water to rinse dust away.

Silicon carbide is a very hard mineral that cuts extremely fast. In fact, it is the fastest-cutting mineral abrasive. It features sharp points that fracture easily, resulting in freshly exposed sharp edges that produce a smooth, professional-looking finish. The mineral has a shorter life, but it produces a superior finish.

More Effective Sanding for More Effective Operations 3M put plenty of science behind the 3M™ Wetordry™ Abrasive Sheet 401Q – and not just to improve your finished work. These abrasive sheets make the entire sanding process easier, from the durability of each sheet during wet sanding to faster cutting to easier buffing for faster production times and less labor cost. It’s another way that 3M helps auto body professionals get the most from their operations.
