OptiGrit Sandpaper Bundle – Long Board PSA Sandpaper for Auto Body & Paint Prep

The OptiGrit Sandpaper Bundle is the perfect abrasive set for blocking, shaping, and refining bodywork and paint surfaces with precision. Designed for use with long sanding blocks, this bundle includes four essential grits to take your project from rough shaping to final surface refinement before primer or paint.

This set includes PSA (Pressure Sensitive Adhesive) sandpaper in 80, 180, 220, and 320 grits, giving you a complete grit progression for efficient material removal and smooth, straight panels. The 80 grit is ideal for shaping filler and leveling high spots, 180 and 220 refine the surface and remove deep scratches, and 320 is perfect for final blocking before primer or sealer.

Built for durability and consistent cut, OptiGrit abrasives are engineered to resist loading and maintain a uniform scratch pattern, helping you achieve flatter panels and better paint results with less effort. The PSA backing ensures quick, secure attachment to long boards and blocking tools, keeping your sandpaper flat and firmly in place while you work.

Whether you’re straightening body panels, blocking primer, or prepping for paint, the OptiGrit Sandpaper Bundle gives you the right grits in one convenient kit for professional-quality results.
