Zona 37-948 3M Wet/Dry Polishing Paper, 8-1/2-Inch X 11-Inch, Assortment Pack One Each 1, 2, 3, 9, 15, and 30 Micron (Limited Edition)

Works great

I've used these for a couple years, and I'm VERY happy with the results.I use them for wet sanding/polishing.Beware - one of the alternate sellers is substituting 3M Tri-M-ite and saying it's the same thing... It is not. (Yes, the Zona one is also made by 3M, but it's not the same)3M Tri-M-Ite goes down to 8000 grit, which converts to 3 Micron. The Zona set goes down to 1 Micron which converts to 14,000 Grit.If you get a pack that doesn't have the Zona logo on it, and says 3M Tri-M-ite.. Return it because that's a cheaper product that you can buy for about half the cost from Wal Mart.That being said, the Zona sheets are a little thicker and go to a finer grit which makes for a better finish.They work very well and last a long time when used wet.They come in a 8.5x11 sheet that's folded in half, but that works for me since I cut it into smaller strips anyway.You can google this chart Grit to Micron conversion.30 Micron = 600 Grit15 Micron = 1,200 Grit9 Micron = 1,800 Grit3 Micron = 8,000 Grit - This is where 3M Tri-M-ite stops.2 Micron = 11,000 Grit1 Micron = 14,000 Grit
