3M 7000045611 Wetordry 281W Disc 8 Inch P500 Grit

Product Description

The 3M 7000045611 is a Wetordry 281W abrasive disc designed for wet or dry finishing on a range of surfaces including paint, e-coat primer, gel coat, and bare metal. Built on a waterproof mesh cloth backing, the disc resists loading and allows consistent stock removal across multiple passes. The aluminum oxide mineral delivers sharp cutting action and fine finish results. At 8 inches in diameter and P500 grit, this disc is suited for intermediate-to-fine finishing stages where surface prep quality directly affects topcoat adhesion. Professional body technicians, painters, and metal fabricators are the primary users.

This disc is intended for hand applications in automotive refinishing, marine gel coat work, and general metal finishing environments. The mesh screen construction allows water and swarf to pass through, reducing clogging during wet sanding. Discs attach to a compatible hand pad or backup pad using clamps or clips, making them practical for contoured surfaces and flat panel work alike. The 8-inch format suits larger panel sections where efficiency matters.

Installation Notes

Attach the disc to a compatible hand pad or backup pad using the integrated clip or clamp system before use. When sanding wet, ensure adequate water flow to carry swarf away from the work surface and prevent surface contamination. Inspect the disc backing for tears or separation before each use and replace if damaged. Dispose of used abrasive media in accordance with local regulations, particularly when sanding lead-based or solvent-borne coatings.
