Chalk Paint Dresser

I have finally decided to try Annie Sloan Chalk Paint and I must say I really like it. I picked up this sweet antique dresser at the antique mall where I rent space. I loved all of the raised details and thought it would be perfect for what I think of as a classic chalk paint look. The colors are Louis Blue and Old White. I sanded the top down and lightly scuffed the rest of the dresser. The blue covered very well in 2 coats. I am still a little iffy about using the wax. I have concerns about the long term durability with a waxed piece. I would love to hear any insight y'all might have in this subject. The top was stained in dark walnut. I love the finished product!
