The cyclododecane shouldn't be able to sublimate through a layer of
metal foil and a layer of wax. How about wrapping the objects coated
with cyclododecane, in a package of polyethylene foil and aluminum
foil, and putting onto the aluminum foil a fixing coating of wax,
e.g Cosmoloid H80 or Paraffin?

The melting point of the wax of course should be lower than the 61
deg. C of cyclododecane while application.

The foils work as a separation layer, it should be possible to take
off the wax later easily--as well as the aluminum foil (in case you
want to make some x-rays).
