The Diablo Flat Sanding Sponge, model DFBLBLOMED01G, is a 5-inch length, 3-inch width, and 1-inch thickness sanding tool with a 60-grit, medium-grade aluminum oxide abrasive. Its foam backing is enhanced with Endura-Bond™ technology, ensuring superior grit adhesion for extended product life and extreme durability. Designed for moderate stock removal and surface preparation before painting, this sponge provides up to three times longer sanding life and material removal compared to standard hand sanding products. The flat edge design allows access to inside corners and hard-to-reach areas, while the full contact design delivers consistent scratch patterns and ultra-smooth finishes. A solvent-free coating helps prevent clogging and pitch buildup, and the flexible foam material resists tearing. It is suitable for use on fiberglass, metal, plastics, and wood surface
