Product Description

The 3M 7000028326 is a wet or dry abrasive sheet designed for fine sanding applications in automotive and surface prep work. Measuring 9 inches x 11 inches with a P400 grit rating, this sheet delivers a consistent scratch pattern on a highly flexible backing. It is suited for wet sanding, fine featheredging, and final sanding passes before priming. Body technicians, painters, and surface prep professionals use this sheet as a finishing step to prepare substrates for primer adhesion with minimal surface defect.
