For Excellent Results, When Excellent Results Arent Easy
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, our 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. Choose sheet sizes of 5-1/2 x 9 inches or 9 x 11 inches to suit specific sanding jobs and reduce the need for tearing.
Light, Smooth, Waterproof Backing
Our 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.
Our Fastest-Cutting Abrasive Mineral
Silicon carbide is a very hard mineral that cuts extremely fast. In fact, it is our 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
We put plenty of science behind our 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.
