Mine had a piece of that thin polyfoam (like Sideshow uses) both top and bottom (between bust & polystyrene) for protection.
Didn't stop a tiny paint scuff on the top of the highest crest though.

This coupled with the fact that they are near perfect circles is what make thing that they are air bubbles underneath the paint on mine. Which would mean that whatever they used to cover it it would still cause said problem just due to the pressure.
