Anyone tried using Sugru on G5 battery replacements?

Typically users who’ve swapped out old-for-new transmitter batteries have used epoxy or a similar hard, water-proof material to re-coat/re-seal casing that was ground off the transmitter. I was wondering if anyone out there’s tried using Sugru. While it’s not as hard and durable as epoxy, that tradeoff may be a better option as it would make it easier to remove the Sugru and do further battery replacements, with less wear-and-tear on the delicate contact tabs for the batteries.

Has anyone out there got experience trying this, or experience with bond Sugru to hard plastics, that may help figure this out? I’ve ordered some anyway, but would love to hear from anyone else who’s experimented with it.
