I heated, like Tom, to well above 160. I do not know how high in F because the thermometer read only to160, but I cooked it for a good 25-30 minutes in a double boiler with a rolling water boil till I could not see any more Carnuba flakes in the mix. It does take a good 24-30 hours to dry per application. I added Japan dryer as per the recipe and Venice turpentine but not regular turpentine. I was thinking a making up another with Tung, rather than BLO, and doubling the Dryer to accelerate the application process and durability.
