You can still get it by mail order I think. Jim Carroll or the Woodsmith. Up your way Woodworks might stock it or Trend.
Just to add to my comments above: in none of these cases was wet-sanding involved. For someone doing kitchen benches or coffee tables this is worth looking into, for grain filling and getting a nice silky feel - but I speak only from a temp period of wet sanding turnings and then only with Hard Burnishing Oil.
