Description
The 3M 7000028328 wet or dry abrasive is a 2000-grit, waterproof sheet measuring 5.5" x 9" and designed for fine automotive wet/dry sanding and paint finishing. This 3M wet/dry sandpaper has a waterproof A-weight backing and fast-cutting silicon carbide mineral, resulting in consistent scratch patterns that buff out cleanly. The 3M 413q sandpaper is ideal for clear coat blending, paint defect removal, and final finish work that requires low-scratch results. The sheet's black silicon-carbide abrasive is designed to cut smoothly while leaving a consistent finish on primer, paint, gel coat, and metal. Durable backing resists loading during wet sanding and increases usable life when compared to non-waterproof papers. This 3M wet or dry abrasive is popular among auto body technicians and detailers because it provides a consistent progression to polishable surfaces. It works with standard finishing workflows and is available in popular sheet sizes for hand sanding and small-block use.
