3M 7100042004 Finesse-it 5 Inch Silicon Carbide Refining Disc

Product Description

The 3M 7100042004 is a Finesse-it Refining Disc designed for paint surface preparation and finish refinement in automotive and industrial coating applications. Built with a silicon carbide mineral on a nonwoven web construction, this 5-inch disc cuts fast while producing a smooth, scratch-free surface. It targets the sand scratches left behind by 1200 and 1500 grade paint leveling steps, accelerating the transition to buffing and polishing. Licensed trades and body shop technicians rely on it for medium to large area refining and repair work where consistent scratch removal is required before the final buff stage.

This disc is well suited for automotive body refinishing, OEM paint correction, gel coat refinement, and primer surface preparation. It performs on paint, clear coat, primer, gel coat, and bare metal substrates. The disc can be run wet or dry, making it adaptable to shop workflow preferences. It is particularly useful in the pre-buff step where water is not practical, allowing the technician to proceed without interruption to the process.

Key Features

• Silicon carbide mineral provides fast cutting action and leaves a smooth surface finish
• Nonwoven web construction resists loading and extends disc service life
• Wet or dry capable for flexible use on paint, clear coat, primer, gel coat, and metal
• Flat abrasive surface efficiently refines sand scratches from 1200 and 1500 grade steps
• Rated for operation up to 7000 RPM
• Sized for medium to large area refining and repair applications

Compatibility

Designed as a replacement and consumable refining disc for use with 5-inch random orbital and rotary finishing tools commonly used in automotive paint correction and surface preparation workflows.

Installation Notes

This disc is installed and used by automotive body technicians and surface finishing professionals. Attach the disc securely to a compatible 5-inch backing pad before operation and confirm the tool RPM rating does not exceed 7000 RPM. Inspect the disc for wear or loading before each use and replace when cutting efficiency declines. Follow shop safety practices including eye protection and dust management when operating dry.
