3M 7000118310 Wetordry File Sheet 413Q 600 Grit 4.5x5.5 in

Product Description

The 3M 7000118310 is a Wetordry abrasive file sheet designed for wet sanding, fine featheredging, and final sanding passes before priming. Built on a waterproof resin bond with a closed-coat silicon carbide abrasive, this sheet holds up in wet applications without degrading. At 4.5x5.5 inches and 600A grit, it fits standard abrasive file boards and delivers consistent cut on the final prep stages of body and surface work. It is sold individually and suited for professional surface prep workflows where grit consistency and waterproof durability matter.

This sheet is used in automotive body shop finishing, marine surface prep, and any trade application requiring wet or dry fine sanding before a primer coat. The 600A grit rating positions it as a final material-removal step, removing light scratches and surface irregularities left by coarser grits. Its closed-coat construction resists loading, keeping the abrasive cutting cleanly through the sanding pass. Typical users include auto body technicians, paint prep specialists, and finishing tradespeople working on metal, fiberglass, or primed substrates.

Installation Notes

This abrasive sheet is installed by hand or onto a compatible file board holder. When wet sanding, keep the work surface and sheet adequately lubricated to prevent heat buildup and loading.
