OptiGrit WetDry 3000 5-1/2" x 9" Waterproof Sanding Sheets – (25/pk)

The OptiGrit 3000 SC Wet/Dry Paper Plain Sheet is designed for super-polish applications. This grit achieves an ultra-fine, mirror-like surface finish when used in final wet sanding stages. Its waterproof silicon carbide abrasive works flawlessly with our Linear Blocking Tools to deliver clarity and depth.

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.
