Frustrated with Annie Sloan Wax

Anyone else having difficulty with waxing on Graphite?  I painted this 25$ chest with Graphite and used only the clear wax on it, it shows smears when I rub my finger across the surface.  

I have used the wax on Duck Egg Blue and Versaille without any problem. I'm wondering if the different colors absorb the wax differently.  

Have you had trouble with the wax on Graphite?  I would love to know the waxing secrets but hate to pay so much for a lesson at an Annie Sloan workshop.  

I'm paying 35$ a quart, I think the least Annie Sloan can do is have reasonably priced classes.
