3M provides a durable, effective sandpaper for each stage of our 3M™ Body Repair System.

About Aluminum Oxide Abrasive
Aluminum oxide is popular because of its fast cut-rate and long life. This natural mineral makes a tough, durable abrasive that self-fractures during use to expose fresh cutting edges where traditional abrasives can quickly wear down. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide is highly effective for sanding and 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.
