Graves and other lapidary suppliers usually offer Dia-lube 20, whereas I recommended Dialube 3000, specifically designed for diamond films. Although Dialube 3000 is formulated for coarser diamond mesh films, it also works well for finishing tool steels on the finer films. Dialube 3000 is a glycerin-based lubricant-extender, can be cleaned with soap and water and contains no silicones. My uses for diamond films are more for optical/metallographic than lapidary, by the way. Diamond charged BATT and ceramic laps leaver flatter facets with sharper edges than films.

The name can be confusing, John. In fact, one Dialube on the market is a suspension that actually contains diamonds. The Dialube I was referring to can be purchased from Pace Technologies.

While I would never recommend a silicone product for woodworking, even with a silicone-bearing lubricant you'd likely have to spill or spray it directly on the wood to cause finishing problems. Wiping the blade should mitigate sufficient transfer.
