3M 7000028327 Wetordry Abrasive Sheet P320 9x11 in

Product Description

The 3M 7000028327 is a Wetordry abrasive sheet designed for wet or dry sanding applications in automotive and industrial finishing work. Measuring 9 inches x 11 inches with a P320 grit rating, this sheet delivers a fine, consistent scratch pattern suited for the last sanding pass before priming, light paint featheredging, and surface prep work. Its flexible backing conforms to contoured surfaces, allowing even abrasive contact across the workpiece. Licensed tradespeople in auto body, paint, and general finishing trades rely on this sheet for controlled material removal at fine grit stages.

This abrasive sheet is used in wet sanding operations where a uniform scratch pattern is critical before primer application. It is well suited for fine featheredging at paint transitions and as the final sanding step on flat or contoured body panels. The flexible backing makes it effective on both flat substrates and curved surfaces. Sheets are sold by the box with a minimum order quantity of 5 units, making this format practical for shop-level restocking.

Installation Notes

Used by auto body technicians and finishing tradespeople during surface prep prior to priming or painting. When wet sanding, keep the surface and sheet adequately lubricated to extend abrasive life and reduce loading. Always sand in a consistent direction or pattern appropriate to the substrate to maintain an even scratch profile. Dispose of used sheets per local shop waste guidelines.
