3M™ Finesse-it™ Imperial™ Wetordry™ Scallop Disc, 05921, 1 3/8 in, 1500, 100 discs per pack, 10 packs per case

3M™ Finesse-it™ Wetordry™ Scallop Abrasive Disc 401Q is engineered with silicon carbide mineral, which is adhered to an A-weight paper backing. Silicon carbide cuts sharp but leaves a bright finish. The A-weight paper backing is the lightest among paper backings, making it desirable because it responds well to the surface without significantly gouging or marring.

Disc 401Q has a pressure-sensitive adhesive backing, which means it adheres to a backup pad (sold separately) with slight manual pressure. The scalloped edge on disc 401Q adds a level of surface forgiveness that operators may otherwise be unable to attain with standard round discs. In this way, the risk of gouging or over cutting is reduced.

3M™ Finesse-it™ Wetordry™ Scallop Abrasive Disc 401Q is great when you want to achieve a final gleam and polish.

3M recommends 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.

Try sanding in a small circular motion with the pad flat against the surface and avoid over-sanding. Use extra caution to prevent over sanding when machine sanding near the edges of panels, which are less flexible and typically have thinner coatings. If preferred, these areas can even be hand sanded. In fact, disc 401Q works well with 3M™ Finesse-it™ Hand Sanding Pad (sold separately).

3M™ Finesse-it™ products are specially-engineered abrasives, compounds, polishes, and buffing pads to be used on OEM and baked refinish paints to remove defects, sand scratches, or swirl marks on a variety of painted surfaces. 3M™ Finesse-it™ products are an integral part of a 3M recommended buffing system for repairing surface defects to clear coats, lacquered wood, solid surfaces, gelcoat, powder coat, industrial paint, acrylic, and glass.
