Can re-stuffing

[Daave]

I have received a whack of new caps for my restoration job, and I have seen lots of pics and whatnot about restuffing the original electrolytic cans, and would like to do that as well. Ive seen 2 ways, one is removing the can and cutting it open, and the other was cutting it off while still on the chassis. But I never understood how you guys were re-attaching the can back together? You have some sort of glue or silicone you are using?
