I don't know if this is a secret or not, but at least it got you to read it. If you use a finishing sander, or a ROS (random orbit sander) with a H/L (hook and loop) pad, you can place on the pad a scotchbrite pad instead of sandpaper, and it works and sticks pretty good. You may want to trim the scotchbrite pad before stickin' it, so the corners won't catch on anything. Let us know how you like it after you try it!

I've been doing that for a long time now. I'll even cut some small strips of sticky back 120 sandpaper and place them in an x pattern across the bottom of the scotchbrite. This helps get any nubs that the scotchbrite pad won't.

Not directly related, but if you have a 150mm (6") ROS try some Festool Platin 2 Pads. Grit equivalent of 500,1000,2000 and a really cool 4000. I don't work for or have any interests in Festool. But these pads are something else.

This is an especially good tip for anyone wishing to use the white-colored (non-abrasive) non-woven/scotchbrite on a ROS. You'll find it's pretty difficult to find a white non-woven disc out there...
