Default Re: Sandpaper grit for stainless?

Ever since I wrote the previous post I've been thinking about how to wet sand stainless using that little Chicago Pneumatics polisher. My current project is made from 22 ga. sheet metal, and the heat from the dry sanding does funny things to it. I have to keep planishing it out. So I tried something today. I use a 3M hook-it soft pad. I took a piece of cloth backed sandpaper and soaked it in warm water for a while to get the glue and the sanding grit off, and then dried it in the sun. I glued it to the soft pad with weatherstrip adhesive, which gave me a surface to glue wet-or-dry sandpaper to, using feathering disk adhesive. The initial test seems to indicate total success. The sheet metal stays cool; wet sanding cuts better than dry; and it's a whole lot cheaper than 50 cents a disc; I can cut maybe 12 three inch discs out of a 50 cent sheet of sandpaper. One downside though: I got soaked; it throws water everywhere.
