I've done this. The transparency issue, I've found, is related to the temperature of the wax when you dip it. The hotter it is, the thinner it is. Thus, the thinner the coating on your bottle will be. Try letting it cool some after melting, and testing the thickness with a toothpick or something. I used a wood skewer for barbecuing that you get in the bags of 100 each. Also - you may already have figured this out, but if you either tilt the bottle or the can when you dip, I find it looks more interesting than a flat/straight across coating. See my picture.
