In your place I would give the GUI workflow a chance:
Exporting scene to Indigo and then create the coated material, tweak it until its perfect and save it out of the GUI.
For each time you re-render the image, you'll need to load and apply the material again, bit of a hassle, but at least you get your renderings done.
