Thanks Joshua. Have several heat guns and meat thermometers. From what I understand it's no longer Parks 50? Every knife making supplier I've found relatively close to me is out of stock on quench oil. Closest I've found is Texas, with oil and shipping it was over $300 for 5 gallons. If you believe it would be better I really don't mind sending the extra money, but if the canola will work as well it is far cheaper locally for me.
