Organoils Hi-Speed Finishing Oils specifically formulated for on-lathe, under-turning-speed finishing. It is a heavy oil which can well deal with the load (fill) requirements of softwoods – you may choose to cut it (with vegetable turpentine) for denser hardwoods. One of its unique ingredients is the rare, Mustard Seed Oil (a well kept Aussie secret until now!) which gives the formulation good slip for the wet-sanding procedure and a silken touch to the finished result.
