3M™ Wetordry™ Sandpaper
Use for wet sanding and dry sanding without switching sandpaper
One Sandpaper for Multiple Auto Body Jobs
Featuring waterproof paper backing, 3M™ Wetordry™ Sandpaper has been a trusted resource in automotive repair since the 1920s. It delivers true versatility — even if you're wet sanding one area and dry sanding the next, our 3M™ Wetordry™ Sandpaper lets you keep moving without having to switch sandpaper. Today you can choose from a complete range of sandpaper grits for jobs ranging from shaping body filler to final paint touchups. Wetordry™ sandpaper features our silicon carbide abrasive, ideal for creating a smooth, refined finish. In fact, it delivers a 10% smoother finish vs. conventional 3M sandpaper. Each sheet is durably resin bonded onto a waterproof paper that helps conform to metal, plastic body filler or fiberglass sanding surfaces, whether by hand or machine. This range of sandpaper for wet or dry sanding is excellent for use in the Fill, Paint and Finish stages of our 3M™ Body Repair System.

Why Wetordry™?
Wet sanding and dry sanding each have their own advantages for sanding effectiveness, time savings and creating a professional grade finish for your auto body repairs. Wet sanding helps keep dust out of the air, and reduces clogging of the sandpaper which can slow you down and cause unwanted scratches in the surface. Wet sanding is generally done during the more refined stages of body repair. Dry sanding tend to remove stock from the surface faster, and saves you from having to continually dry the surface — you can instantly check the progress of your work. Our 3M™ Wetordry™ Sandpaper saves you time and hassle right from the start. It allows you to keep just one sandpaper on hand and to eliminate extra time switching between sandpapers, even if your project requires both dry and wet sanding.

Silicon Carbide — Sharp Abrasive with a Refined touchups
3M™ Wetordry™ Sandpaper in finer grits features silicon carbide — a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep, smoothing of clear coats and as an alternative to compounding. Users only need to apply light pressure to obtain a consistent scratch pattern desirable for final finishing.

About the 3M™ Body Repair System
Even a small repair can seem complex at first. So 3M's Body Repair System simplifies the entire automotive body repair process by dividing it into four stages:

Stage 1 — Prepare. This stage includes pulling dents, removal of paint and rust and efficient, effective masking of the area.

Stage 2 — Fill. This stage involves patching holes with reinforced filler and smoothing and shaping filler before painting.

Stage 3 — Paint. This stage includes painting the area and blending and smoothing primer and paint.

Stage 4 — Finish. The final stage for showroom-grade results: removing small defects, sealing and polishing clear coats and other painted surfaces.

3M supplies premium products such as abrasives, tapes, body fillers and tools for every stage. This system helps you work easily, efficiently and successfully across the entire body repair process.
