3M™ WetorDry™ Sandpaper 331Q

The flawless result starts with the ideal sandpaper
Made with aluminum oxide mineral, 3M Sandpaper 331Q is durable and flexible that facilitates its use during wet sanding applications in automotive repair. It has waterproof treatment on the paper, which is also resistant to sheeling and cracking. This sandpaper was produced using materials specially developed for wet applications on surfaces that require grinding and finishing processes.

How to use your Sandpaper Sheet
Cut the sheet according to the size of your sanding block or according to your manual needs. Start sanding, always using clean water for lubrication. Use a sequence of suitable grains, according to your process, in order to guarantee the removal of the scratches from the previous grain at each step. For a better application, in roughing operations make oriented movements (horizontal and vertical movements) and for finishing phases make circular movements.
