After an exhaustive search for Parks AAA and coming up empty handed in my area (northern, VA.), I am thinking of trying the McMaster/Carr quenching oil. Anybody have any experience with it ? I am working with O1 exclusively. I would rather use a bonefided quenching oil designed for the task and not mineral/canola/peanut oil if I can help it.
