Product Description

The 3M 7000028329 is a wet-or-dry abrasive sheet designed for fine finishing and surface preparation tasks requiring ultra-fine cutting action. Graded at 1500A, this sheet delivers consistent scratch patterns suitable for sanding between finish coats, removing minor surface defects, and preparing surfaces before polishing. Each sheet measures 5.5 inches x 9 inches and can be used wet or dry depending on the application. Cases are packed with 50 sheets per sleeve and 5 sleeves per case, for a total of 250 sheets. The case weight is 3 pounds.

These sheets are suited for trade and production environments where consistent ultra-fine abrasive performance is required across multiple passes. Typical applications include finish sanding on metal, painted surfaces, gelcoat, and composites. They are commonly used by automotive refinishing technicians, body shop professionals, and trade workers performing prep work prior to topcoat or clear coat application. The wet sanding capability helps reduce heat buildup and keeps the abrasive surface clear during use.
