I finally got around to fixing mine a few weeks back as my admiral continually over-opens it, this eventually meant a special 'touch' to get enough hot water for the shower. It was a five minute job, modern taps are rubbish!
I wouldn't waste a good set of molies though, they will never be the same again.
Sure does. It certainly doesn't build muscles when used as shower gel!
Seriously - if you spray it on, wrap fenders in cling film and leave overnight they come up really clean. Actually same thing works for oven cleaner (on ovens, obviously) and paint stripper. They all dry out before they have exhausted their chemagical powers.
