3M 7000000591 Softback Sanding Sponge Microfine 1200-1500 Grit

Product Description

The 3M 7000000591 is a microfine softback sanding sponge designed for finish sanding and surface prep work in automotive, woodworking, and general trade applications. Measuring 4.5 inches x 5.5 inches, it is coated with aluminum oxide mineral across a microfine grit range of 1200 to 1500. The flexible foam backing allows the sponge to conform to contoured and recessed surfaces where flat sheet abrasives cannot reach effectively. It can be used wet or dry, making it suitable for both waterborne and solvent-based finishing systems. Weighing 0.62 pounds per box, this sponge is built for repeated professional use.

This sanding sponge is well suited for finish sanding in automotive bodywork, including sanding around headlight openings, door handles, and door jambs. It is also used in trim carpentry, cabinetry finishing, and other trades requiring fine surface preparation on curved or irregular profiles. The microfine grit range makes it appropriate for final scuff passes before topcoat application and for eliminating light surface marks left by fingers or handling.

Installation Notes

No power tools or fasteners are required for use. When sanding wet, ensure the substrate and any surrounding finishes are compatible with water exposure before proceeding.
