3M Wet-Or-Dry Tri-M-Ite Sandpaper Sheets

3M Wet-Or-Dry Tri-M-Ite sandpaper sheets are silicon carbide abrasive sheets for wet or dry sanding. They suit automotive, marine, and general finishing work. The closed-coat silicon carbide surface is bonded with waterproof resin to a flexible paper backing. The sheets work well for sanding old finishes, fine featheredging, and surface work.

Key Features:

• Silicon carbide mineral: Sharp mineral points fracture during use and expose fresh cutting edges. This gives a fast cut and a smooth, consistent finish.
• Wet or dry use: Sand with water to rinse away debris. This helps prevent clogging and cuts down on airborne dust. You can also sand dry.
• Waterproof paper backing: The backing is flexible enough for hand sanding and contours. It is also durable enough for machine sanding.
• Resin bond: The waterproof resin bond resists heat build-up and deterioration.
• Closed-coat surface: The abrasive coverage is dense and gives an even scratch pattern.
• Versatile applications: Use on paint, primer, sealer, gel coat, plastic filler, bare metal, wood, and fiberglass.
• Easy to size: The sheets can be cut or folded to fit the task.

These sheets are a good choice for paint prep, primer and sealer sanding, scratch refinement, and finishing work. Choose the grit that matches your job, from heavier stock removal to fine finishing.
