Abrasive is built on a choice of paper backing from light A-weight paper to heavier D-weight paper for jobs requiring extra support. All of it is resin bonded to resist heat and to reduce dust clogging, helping lengthen the life of each sheet. Choose 3M™ Sandpaper in a range of abrasive grades for jobs ranging from stripping paint to fine featheredging. This sandpaper works great with Bondo® Body Filler. 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.
