Hi Dom,
it might not be perfect, but I have used silicone rubber to attach loose bases. It's best if you can get the stuff that is not acetic cured, but in my experience even the acetic disperses reasonably quickly if you don't use excessive amounts of the stuff and keep the component well ventilated as it cures. So far I've never had any corrosion trouble and it's always been strong enough.
You can get high a temperature silicone compound which even works reasonably well on hot valve bases and top caps... and this produces no acetic acid as it sets.
Almost guaranteed to remain flexible but sticks like... er... silicone rubber !
