3M 7000148222 Wetordry Abrasive Sheet 320A 9x11 in

Product Description

The 3M 7000148222 is a silicon carbide abrasive sheet designed for wet or dry sanding applications in automotive and surface preparation work. Built on a waterproof resin bond with a closed-coat construction, this 320A-grit sheet delivers consistent cut and finish control during fine featheredging, final sanding before priming, and the removal of old finishes. At 9 inches by 11 inches, the sheet is a standard hand-sanding size that works with or without a backing block. The silicon carbide mineral cuts cleanly on both metal and painted surfaces, making it a reliable choice for body shop technicians and finishing professionals.

This abrasive sheet is suited for automotive refinishing environments where a fine final scratch pattern is required before primer application. It performs in wet sanding operations where water is used as a lubricant to reduce loading and improve surface smoothness. Typical applications include featheredging paint edges, knocking down primer coats, and prepping bare or coated metal panels for the next finishing stage. The waterproof resin bond holds up to prolonged water exposure without delamination or sheet breakdown.

Key Features

Compatibility

Designed as a general-purpose abrasive sheet for wet or dry hand sanding in automotive refinishing and surface preparation applications.

Installation Notes

This product is typically used by automotive body technicians and painters as part of a multi-stage surface preparation process. When wet sanding, keep the surface and sheet saturated to minimize loading and achieve a consistent scratch pattern. Wear appropriate respiratory and eye protection when dry sanding to limit dust exposure. Follow all applicable shop safety protocols and finish manufacturer guidelines for surface prep requirements before priming.
