Recommended Applications

• Automotive Finishing: Paint leveling, clear coat sanding, wet sanding between coats
• Metal Polishing: Stainless steel, aluminum, brass, and other metals (use with oil)
• Woodworking: Ultra-fine finishing on lacquer, varnish, and polyurethane
• Glass & Ceramics: Smoothing and polishing hard, non-porous surfaces
• Plastic & Composites: Fine finishing on fiberglass, acrylic, and other plastics
• Stone & Marble: Polishing and smoothing natural and engineered stone

Wet vs. Dry Sanding Guide

• Wet Sanding (with water): Produces ultra-smooth finishes on paint and clear coats, eliminates dust, prevents heat buildup, ideal for automotive work
• Oil Sanding: Best for smoothing and polishing metals, provides lubrication and corrosion protection
• Dry Sanding: Suitable for quick touch-ups and situations where water isn't practical

Grit Range & Applications

• 60-120 Grit: Paint removal, heavy leveling, rust removal
• 150-320 Grit: General smoothing, between-coat sanding
• 400-600 Grit: Fine finishing, final prep before polishing
• 800-1200 Grit: Ultra-fine finishing, clear coat leveling
• 1500-2500 Grit: Mirror finish polishing, final buffing preparation

Professional Tips

• Keep sheets wet during use for best results and longest life
• Use progressive grits (don't skip more than one grit level)
• Rinse frequently to remove sanding residue
• Store unused sheets in a dry location to maintain flexibility
