I found this on Amazon:
[h=1]3M Stikit Paper Sheet Roll 426U, Silicon Carbide, 2-3/4" Width x 25 yds Length, 80 Grit, Gray (Pack of 1) $18.32[/h]
The 3m Gold is 62.79 for 25 yards on Amazon Prime. I used to get the same thing from my local guy for about $46. I've never tried this white 3M paper. It's hard to believe that 3m would sell something so much cheaper if it actually works. Then no one would by their gold.
