Like Painting the Forth Rail Bridge

A popular metaphor based on painting and decorating
and one which will soon be redundant as thanks to the
continual development of paints and coatings with a much greater life cycle than previously and with which Rab the Painter (pictured right) and his fellow painters have recently used to completely renovate all of the metal work on the now 122 year old bridge there will be no need to paint the bridge on a continuous never ending loop. So in future tasks such as, washing the dishes, weeding the garden, tidying a child's bedroom and of course organising all the files and photos on your computer will no longer be comparable to "Painting the Forth Rail Bridge" and another time served expression will vanish from our language.
