Norton Sandpaper, ProSand Premium 400 Grit Sand-Paper, Fine Sandpaper for Metal and Wood, Pack of 20 Sanding Sheets

great quality

I use this for both wood and metal. It’s the best I’ve found, by far.

The longevity and consistency of this paper beats the pants off of most others. It's probably even just a hair better than equivalent 3M WetOrDry paper. Value of buying the big pack is excellent. Would buy again (although probably not for years as the 20 sheet will take quite a long time to go through with how long a sheet lasts!)

Sanding wooden bowls , and wooden Santa Claus , refinishing all types of wooden projects.

I use this for painting with pastels. It's absolutely fantastic as a lesser expensive way to get the surface you need. While sanded pastel paper is thicker, this isn't. It's much thinner. However, the pastel covers the surface. You could mount the paper first if you want a thicker or harder board. It's definitely worth a try for all the practice paintings. I have even framed many of them on this paper.

This is excellent sandpaper for woodturning. I don't know if this abrasive is friable or not but it doesn't break down like the "old-fashioned" stuff. The backing holds up well even when I'm sanding with mineral oil and bee's wax.

Use this on all my projects.

The backing holds up well, wet or dry and it seems to stay "sharp" longer than other papers I've tried.
