  1. I have just ordered about 10 gallons of polymer. I will let you know how it works on 4140. Probably about end of Jan by the time I get set up and run it. We buy polymer coolant for our grinders, and perhaps had an in to buy a smaller amount. I'll keep you posted on our progress. Thanks
  2. My big reason for looking for a polymer quench is the reduction of fire hazard, and smoke/fumes from the oil. How is you oil in this regard? I will be hardening 4140 in it so from about 1575 F to 200 F in oil Thanks
  3. Do you still have any of the quench G polymer available?
