One of my kegs have a very brittle rubber handle. Them I realized that I don't know if it is just a rubber piece glued to the keg body or if there is any sort of metal underneath.
If there is just a rubber piece, what to do to repair/recover it?
Took a bit of searching around GIS, but as I thought, looks like there's nothing under there:
For repair/recover, best option would probably be to clean both sides well with alcohol or Ronsonol, and use something like JB Weld to 'glue' it back on. Might help to scuff up both sides (maybe with sandpaper) to help it adhere, too.
Since we're talking about the handles which need to bear the whole weight of a full keg though, I would be very careful carrying it around.
