When a project necessitates exceptional results, look to 3M™Sandpaper for your surface finishing solutions. This 40 grit product is made with aluminum oxide, a tough and versatile mineral abrasive. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives quickly wear down with use. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide is highly effective for sanding and finishing.

3M™ Sandpaper, 40 grit, is an essential part of the 3M Body Repair System.

About the 3M Body Repair System

The 3M Body Repair System connects two great brands and demonstrates how 3M & Bondo® branded products work together to achieve an excellent body repair. The four-stage process highlights the different steps for repairing everything from a paint scratch to a small dent to a patch of rustred out metal.

The stages explain how products from different categories – such as abrasives, tapes, body filler and tools – work together during each stage of a repair.
Stage 1 products are for removal of material in damaged areas in preparation for treatments and repair. These products help mask the area and remove paint and rust. Stage 2 products are for removing dents, treating and repairing rust, reinforcing holes in preparation for filler application, pulling dents patching holes and making small repairs.

Stage 3 products are for applying body filler, feathering, sanding, and re-applying. These products are for preparing the surface for primer. Stage 4 products are for the final step -- sealing with primer, paint and polish.
