I usually make the new inner lining from fishpaper, as the old one does not necessarily survives, plus the new caps, unlike the old ones, have leads that can touch through the seams before potting....I would prefer the old one, but it is not always possible for me.

PS. I posted several radios threads that required tone ctl rebuilding, and every time when potting, I create a little dome from the same fishpaper over the caps' bodies. I do not fully enclose them, but make it enough to prevent massive quantity of molten plastic from enveloping the caps, to prevent a possible cap damage by the temperature. There will be enough hot glue to still go in a bit and to stabilize the bodies, and it will coat leads and wires to keep everything sealed and insulated.
