The Wima MP3 suppression caps are encapsulated in transparent epoxy. It is possible to see which lead connects to the outside of the core by inspecting with a good magnifying glass. There is some sort of bonding agent present around one of the leads, and I assume it is on the outside of the metallized paper winding.

These caps have the printing on a foil piece that covers, but does not connect to, the core. The AC voltmeter test gives identical results no matter how I hold and connect the leads, and I believe the foil piece acts as a shield.
