For Excellent Results, When Excellent Results Aren’t 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.

The Science Behind Disc 401Q
We engineer our 3M™ Finesse-it™ Wetordry™ Scallop Abrasive Disc 401Q with silicon carbide mineral, which is adhered to an A-weight paper backing. A synthetic mineral, silicon carbide cuts sharp but leaves a bright finish. Its ability to finish fine is one of the primary reasons we chose this mineral for disc 401Q. The A-weight paper backing is the lightest among paper backings. This backing is desirable, because — given its lightness and malleability — it will respond well to the surface without significantly gouging or marring.

Additionally, disc 401Q has a pressure-sensitive adhesive backing, which means it adheres to a backup pad (sold separately) with slight manual pressure. Removing the disc is as simple as securing it — simply peel it away from the backup pad. Altogether, this attachment system expedites tool connections. It makes disc changeouts fast and easy, so you can focus on what matters most: your work.

The scalloped edge on disc 401Q adds a level of surface forgiveness that operators may otherwise be unable to attain with standard round discs. Because the edges are scalloped, if the disc accidentally tilts or abrades with its edge, it will be more forgiving than if it were a rounded edge. In this way, the risk of gouging or over cutting is reduced.

Keeping up Appearances
Sanding an automotive surface can be challenging; you want to repair or enhance the body’s appearance without causing unnecessary damage. There are some steps you can take to maximize abrasive service life and approach the substrate with finesse.

For example, we recommend using water as a lubricant during sanding and spraying the abrasive disc with water before and after sanding each spot; it helps keep the disc clean and extend service life. 3M™ Wetordry™ products are backed with a proprietary durable waterproof paper backing that supports both wet and dry applications. Lighter weight than cloth, and smooth rather than textured, 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 from the workpiece and the abrasive surface.
