3M 7100042005 Finesse-it Refining Disc 6 Inch Fine Grit

Product Description

The 3M 7100042005 is a Finesse-it Refining Disc designed to remove sand scratches left behind by 1200 and 1500 grade paint leveling steps. Built with a silicon carbide mineral on a nonwoven web backing, this 6-inch disc cuts quickly while producing a smooth, consistent surface finish. Rated to 5000 RPM, it is suited for use on paint, clear coat, primer, gel coat, and bare metal. Body shop technicians and automotive finishing professionals are the primary installers of this disc in production and repair workflows.

This disc is built for medium to large area refining and repair work. Its flat abrasive surface makes it effective at quickly leveling surface texture across broad panels. The nonwoven web construction resists loading, which extends usable disc life compared to conventional coated abrasives. The disc can be run wet or dry, including in a dry pre-buff step, giving technicians flexibility across different finishing stages.

Installation Notes

This disc is installed by automotive finishing technicians using standard 6-inch hook-and-loop or adhesive backing pads. Ensure the backing pad and disc are fully seated before operating the tool.
