In my experience using beeswax in contact with platinum cure silicons will cause the silicone not to set properly. For the record the molds were for a different purpose.
When using 100% pure beeswax, it seems to be an issue with just Smooth On Dragon Skin. Is that what you used? I've added a note to the article about it.
I've also had a few folk think they were using pure bees wax, but noticed when they poked around on the label after that it wasn't actually, it's often mixed with other oils and waxes.
