I tried coating my gummies with beeswax but it was a failure. First, I melted beeswax and tried to pour it in a spray bottle but it hardened so fast. Also, I tried coating them by just putting them in the beeswax but the gummies dissolved with the wax because of the heat. I tried to coat them with a mix of olive oil and wax (2/3+1/3) but it wasn't perfect, there were some little pieces of wax on the gummies.
From what I understand the way waxy coatings are applied is actually by adding your candies and powdered wax to a tumbler.
Claire from bon appetit tried to accomplish it by abusing a salad spinner to make gourmet jelly beans and m&ms. Ann Reason from How to Cook That used a children's toy rock tumbler to apply a cocoa butter coating to some jelly beans.
