Buying Guide: How To Choose Your 400 Grit Sanding Sponge

- Durability and returnability: High-density sponges with durable abrasives offer longer life; consider sets with washable components for reuse.
- Flexibility and shape: Bendable or cut-to-shape sponges help reach curves, edges, and contours without gouging.
