I'm using the Ecosoya CB135 & I usually have to zap it, sometimes more than once to get a nice smooth top. However I've noticed that the tins have been setting up much smoother than my jars, haven't a clue why. I can't comment on frosting tho as my soy is usually undyed. I find the throw much better with this wax than with the Ecosoya CBA & cure time is less too. Good luck with the new wax. Sally.
