3M™ Blue Sandpaper 31581-8, 800 Grit, 3.66 in x 9 in, 8 Sheets/Pack, 20 Packs/Case

3M™ Blue Sandpaper uses a ceramic mineral blend for excellent cutting performance, helping you get more work done with fewer sheets. Additionally, 3M™ Blue Sandpaper is easy to attach and remove, making it perfect for use with a 3M™ Sanding Block.

Resistant to both clogging and loading, 3M™ Blue Sandpaper places an emphasis on material longevity. This tough abrasive self-fractures to expose new edges that allow for high durability, all while helping reduce the need for dust removal. Especially when used with Bondo® Body Filler, these sharp minerals provide a refined finish for excellent results in auto body repair.
