Actually a modeler by the name of Steve Riojas did this for a Frankenstein and the Dr.s diorama. If memory serves he actually tacked the top and the bottom of the jugs with glue. He made the parts fit as tight as possible and then used a generous amount of Futura floor wax to literally merge and blend the seams by filling it with the wax. I could'nt find the seam line on any of the bottles that he did. I'd experiment first.
