3M 7100045387 Foam Abrasive Disc 3 Inch P3000 Grit

Product Description

The 3M 7100045387 is a 3-inch foam-backed abrasive disc designed for fine finish work on painted surfaces. It uses a three-dimensional mineral structure distributed uniformly across the disc face, allowing the abrasive to wear evenly and deliver a consistent scratch pattern at P3000 grit. The result is faster cut with less variation between passes, which reduces the time required for the compounding stage. Licensed paint and body technicians use this disc when refining sand scratches prior to final polish. The foam backing conforms to contoured panels, making it suitable for curved body sections as well as flat surfaces.

This disc is intended for automotive and collision refinishing applications where a high-gloss, deep-color paint finish is the end goal. It fits into a multi-step paint correction workflow, targeting the scratch-refinement stage after block sanding and before machine compounding or polishing. The Trizact disc is part of the 3M Perfect-It Paint Finishing System, which sequences abrasive and polishing steps to minimize total labor and material consumption. Typical users include body shop technicians and professional detailers working on OEM and refinished clear-coat systems.

Key Features

• P3000 grit three-dimensional mineral structure for fast cut and consistent finish in one pass
• Uniform abrasive distribution promotes even wear and extended disc life
• Foam backing conforms to curved and contoured painted surfaces
• Hook-and-loop attachment system allows rapid disc changes with compatible hook pads and soft interface pads
• Designed to reduce or eliminate extra compounding stages when used in the correct sequence

Compatibility

Designed for use with hook-and-loop disc pads and soft interface pads as part of the 3M Perfect-It Paint Finishing System. Verify pad diameter and attachment type before use.

Installation Notes

This disc is installed and removed by hand using the hook-and-loop backing — no tools required for disc changes. Ensure the backing pad surface is clean and free of debris before attaching the disc to maintain proper adhesion and a flat working surface. Operate the disc at the speed recommended for the backing pad in use; exceeding pad-rated RPM can cause uneven wear or disc separation. Surface preparation work on vehicle paint systems should follow applicable shop safety practices, including appropriate respiratory protection when sanding or polishing.
