I have used the J223 and I like the easiness of it,,,although sometimes you need to re-pour. It burns good with the low smoke 60 zinc, I use the wide mouth Kerr pint and half pints. Great Hot and Cold throw,,the only issue I have with this wax is the color,,,it is so opaque and creamy that you just dont achieve the dark colors you want,,I have tried,,,other then that its a great wax. I have gone back to the 4786 as I like this wax,,,has great hot/cold throw and sharp colors. JMO:yes:
