OptiGrit WetDry P1500 5-1/2" x 9" Waterproof Sanding Sheets – (25/pk)

The OptiGrit P1500 SC Wet/Dry Paper Plain Sheet is ideal for cutting down orange peel and prepping surfaces for buffing. This ultra-fine grit delivers precise control during wet sanding, thanks to its waterproof silicon carbide abrasive. Paired with our Linear Blocking Tools, it provides an even, buff-ready surface.

The OptiGrit Waterproof Sanding Sheets are designed for both wet and dry sanding, giving you professional results whether you’re blocking panels, smoothing primer, or leveling clearcoat. Each sheet measures 5-1/2" x 9", the perfect size for use with sanding blocks — especially our Linear Blocking Tools for the ultimate precision finish.

Because they’re waterproof, you can use them with water to reduce dust and keep the abrasive cutting sharp, making the sheets last longer. Whether you’re shaping body filler, prepping primer, or finishing paintwork, OptiGrit delivers consistent performance you can count on.
