3M Marine 09283 Sanding Supplies The 3M Marine 09283 Hookit Dust-Free Gold Disc is a premium 6-inch sanding disc featuring 150-grit abrasive designed for professional-quality surface preparation on boats and marine projects. This box of 100 discs provides long-lasting performance for sanding fiberglass, gelcoat, paint, primer, wood, and other marine surfaces, delivering consistent results and excellent material removal rates throughout the disc's life. The dust-free design features a multi-hole pattern that maximizes dust extraction when used with vacuum-equipped sanders, keeping your work surface clean and visible while reducing airborne dust that can contaminate fresh paint or create health hazards. Effective dust removal also extends disc life by preventing dust buildup that can clog the abrasive and reduce cutting efficiency. The cleaner work environment improves finish quality and makes cleanup faster and easier. The 150-grit rating provides a medium-fine abrasive that's ideal for smoothing surfaces after initial shaping, removing light scratches and imperfections, preparing surfaces for primer or paint, and achieving a smooth finish before final sanding steps. This versatile grit works well for a wide range of marine applications from hull fairing and gelcoat repair to woodwork finishing and paint preparation. The Hookit backing system features a hook-and-loop attachment that allows quick, tool-free disc changes on compatible sanders. Simply press the disc onto the backing pad to attach, and pull it off when worn or when changing grits. This convenient system saves time during projects requiring frequent disc changes and ensures the disc stays securely attached during aggressive sanding operations. The gold-colored aluminum oxide abrasive provides excellent durability and consistent cutting performance, resisting breakdown and maintaining sharp cutting edges longer than economy abrasives. The resin bond system holds the abrasive particles securely while providing flexibility to conform to contoured surfaces without cracking or shedding grit. Whether you're preparing surfaces for painting, smoothing gelcoat repairs, fairing hulls, or finishing woodwork, these 3M Hookit Dust-Free Gold Discs deliver the performance, durability, and clean operation needed for professional-quality marine finishing work. Specifications: Disc diameter: 6 inches Grit: 150 (medium-fine) Quantity: 100 discs per box Dust-free multi-hole pattern Hookit hook-and-loop backing Gold aluminum oxide abrasive Suitable for fiberglass, gelcoat, paint, primer, and wood Compatible with vacuum-equipped sanders Long-lasting performance Normalized SKU: 09283UPC Code: 068060063168
