Well, it's not going to improve its life, and it does mean that when it
goes, it will make a louder bang, since it will be harder for the
electrolyte to get out. Silicone isn't terribly strong, so it won't
stop it. If you look at most electrolytic caps, you'll see they're
designed to come apart under stress without turning into small
grenades; the ends are scored, or the seals are deliberately made less
strong than
the aluminium case.
