Can anyone tell the best sandpaper and how to attach it to one of these multi sanders the one with round le v-shaped etc ??
I have tried using the sticky back paper and it will not conform to the different shapes and stay in the grooves..... Please help Thank you KJA

I use 3M brand sandpaper found at your local Lowe's or hardware store (heck, you can even buy it at wal-mart). I use 3M super 77 spray adhesive to attach it. cut your sand paper, spray the back of the paper, let it set for a minute or so, and then attach it to your sander. I've found that it holds very well, but you can still peel it off when it's time to replace the sandpaper. then use a little bit of acetone on a paper towel to clean the gum off the sander before attaching the next piece.
