agessive or bare wood sanding: dry paper

fine cut finished wood: wet/dry- Wet paper helps carry away the finish soilds in solution and the water also keeps the heat down on the finish.

It is pretty hard to find dry paper in grits over 400 anyway.

I use 3m gold 100-330 (dry)....3m wet/dry 400-800 (dry or wet depending on task)...Micromesh 1500-12000 (mostly wet)MichaelP38706.4333796296

I use the 3M gold 400 and 600 in the finishing process. I think that 800 is even available from Stew Mac. I really like this stuff for sanding lac as it is no load paper. I also have regular 400, 600, and 800 dry paper that I get from www.sandpaper.ca. I buy my 3M gold from Lee Valley, both are Canadian companies.

I level the finish with 400 and then go to the 600 in 3M. Then it is 800-1000-1500 using wet/dry paper (which I am using wet). Then we hit the buffing wheel at med-fine-super fine.

I have noticed that the quality of sandpaper makes a big difference. When I first started I was buying my paper at the local hardware store. But that cheap paper is not near as good as the stuff I am using now. The quality paper cuts faster, more consistent and lasts way longer. It costs a bit more, but is defiantly worth it.

Just a note for those who don't know--Lee Valley has a U.S. outlet, New York I think, and we only have to pay in-country shipping rates. Good stuff there!

I wasn't aware that Lee Valley had a US outlet. Good to know.

I get my 3M Gold paper from the local auto paint supply store. They stock 400, 600 and 800 grits. Last time I looked they were cheaper than Stu Mac and I don't have to pay shipping.

Norton has dry paper in grits above 400. Works great too!
