3M 7000120121 Wetordry Abrasive Sheet 1200 Grit

Product Description

The 3M 7000120121 Wetordry Abrasive Sheet 434Q is a silicon carbide wet-or-dry sanding sheet designed for finish-stage surface preparation in auto body repair and refinishing work. Built on a heavier C-weight paper backing, it resists curling during extended use and holds up under both wet and dry sanding conditions. At 1200 grit, it is suited for leveling orange peel, dust nibs, and paint runs across all common paint systems, including refinish lacquer. Each sheet measures 5.5 inches x 9 inches and is sold in a box quantity. Painters, body technicians, and detailers reach for this sheet when consistency and a smooth final surface are the priority.

This abrasive sheet is used in automotive refinishing environments for final-stage paint correction and light surface prep. Common applications include leveling texture defects before buffing, removing dust contamination from clear coat, and fine sanding between coats on lacquer or basecoat-clearcoat systems. The 1200-grit cut is aggressive enough to remove surface imperfections quickly while leaving a scratch pattern fine enough for compounding or polishing follow-up steps. It performs on both horizontal and vertical panels.

Installation Notes

For wet sanding, soak sheets in clean water for several minutes before use to improve flexibility and reduce loading. Ensure adequate ventilation when dry sanding painted surfaces. When used on a vehicle, mask adjacent panels and trim to avoid unintended abrasion. Dispose of used abrasive sheets and sanding slurry in accordance with local waste regulations, particularly when sanding lead-based or specialty coatings.
