They spray this liberally on the inside of the can. It has a waxy consistency. Definitely not talcum powder.
Waxy? The OP describes it as "chalky", not waxy...it can't be both. I would not be surprised if it was chalk because the rubber component is probably made many months (or years even) prior to final assembly in the end product and rubber, over time, has a tendency to revert back to it's sticky natural state. And talcum is the cheapest, most common method of preventing sticking.
If it's some kind of spray for the metal canister to prevent oxidation, they would need to do it without the filter media and other components in place. Why would they insert the media and everything else and then spray that? The media and rubber don't rust. Doesn't make sense...
Watch these filters being made at Fram. I don't see anywhere where they "spray" a waxy white residue. It does however show a worker placing bulk rubber seals on.

This is a very good video but the SuperTech filters are made by Champ Labs not Fram. I have cut open a good number of eCores and Champ does spray the inside of the can with "something".
