When a project necessitates exceptional results, look to 3M™ Wetordry™ Sandpaper for your surface finishing solutions. 3M™ Wetordry™ abrasive products may be used for either wet or dry sanding applications, which allows you to switch between both methods with one sandpaper. Wet sanding and dry sanding each have their own advantages. Dry sanding saves you from having to dry the surface to check the progress of your work. Wet sanding works more quickly, holds down the dust and reduces clogging of the sandpaper. The flexible backing of this abrasive is perfect for sanding and finishing plastics, metal, body fillers, glaze, primer and clear coat with a more consistent scratch pattern.

3M™ Wetordry™ Sandpaper, 320 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.
