OptiGrit WetDry 600 Grit 5-1/2" x 9" Waterproof Sanding Sheets – (5/pk)

The OptiGrit 600 SC Wet/Dry Sanding Sheets are built for controlled cutting, surface leveling, and precision prep work where consistency matters. This grit is ideal for refining clearcoat, knocking down imperfections, and preparing surfaces for the next stage—making it a go-to for both professionals and serious DIYers.

Designed with a durable waterproof silicon carbide abrasive, these sheets perform exceptionally well in both wet and dry sanding applications. When used wet, they reduce dust, minimize clogging, and maintain a sharper, more consistent cut—perfect for achieving a smooth, uniform surface without deep scratching.

The 5-1/2" x 9" size fits perfectly with sanding blocks—especially Linear Blocking Tools—giving you better control, even pressure distribution, and a flatter finish across panels.

This 600 grit pack is especially useful for:

• Headlight refinishing prep – removing oxidation and leveling prior sanding steps
• Flow coat prep – scuffing and refining clearcoat before re-clearing
• Denibbing basecoat or sealer – knocking down dust nibs and minor imperfections without damaging the surface

Whether you’re refining clear, prepping for additional coats, or correcting minor defects, OptiGrit delivers reliable, professional-grade results.
