- Top-Quality EVA Foam: Our soft EVA foam closely adheres to edges, reducing burn-through and skipping. This helps achieve precision sanding without damaging the surface. - Superior Durability: 5 inch interface pads with waterproof adhesive hook firmly hold the foam and sanding disc together. They are designed for both wet and dry sanding and won’t come apart under pressure. - Enhanced Flexibility: The hook and loop backing pad bridges the gap between your sandpaper and orbital sander, delivering optimal results. Ideal for contoured and curved surfaces on cars, boats, and furniture, with smooth operation and reduced vibration. - Versatile Hook & Loop System: Dual-sided design with a hook face for easy sanding disc attachment and a loop face for secure pad placement. Compatible with a wide range of sanding discs for quick replacements and improved efficiency. Use scenarios: - Sand curved car panels and trim to maintain shape and achieve a smooth finish. - Sand boat hulls or decks with contoured surfaces for even, consistent results. - Restore furniture with curved edges and profiles for a clean, professional look.
