3M 7000000589 Softback Sanding Sponge Fine 4.5x5.5 in

Product Description

The 3M 7000000589 is a fine-grit softback sanding sponge designed for surface preparation work in automotive, finishing, and general trade applications. Coated with aluminum oxide mineral across a fine grade range of 320 to 400, the flexible foam pad conforms to curved and contoured surfaces where flat abrasives cannot reach. Measuring 4.5 inches by 5.5 inches, it provides a practical working surface for controlled hand sanding. The construction helps reduce finger pressure marks on finished surfaces and is suitable for both wet and dry use, making it a versatile option for technicians working across a range of refinishing tasks.

This sanding sponge is well-suited for automotive body prep, paintwork finishing, and detail work around tight geometry. Common applications include sanding around headlight openings, door handles, door jambs, and similar hard-to-reach contours. It is used by auto body technicians, painters, and finishing tradespeople who need consistent abrasive contact on irregular surfaces. The wet or dry capability makes it compatible with waterborne and solvent-based finishing processes.

Installation Notes

No power tools or mechanical fastening is required for use.
