3M 34800 P400 Grit Hookit™ Flexible Abrasive Dust Free Disc (6 Inch, 25 Count) is a professional-grade sanding disc designed for surface refinement and primer preparation in automotive collision repair and refinishing applications. The P400 grit precision abrasive delivers a uniform scratch pattern, making it ideal for primer sanding, panel preparation, and surface refinement prior to sealer or topcoat application. Engineered with a flexible backing and dust-free hole pattern, the disc is designed for use with compatible vacuum-assisted sanding systems to help reduce airborne dust and improve sanding efficiency. The flexible construction allows the disc to conform to panel contours for consistent contact, while the Hookit™ hook-and-loop backing enables fast disc changes and secure attachment to standard 6-inch random orbital sanders.
