It is, and for less money. The various electronic and industrial supply outlets carry it, for example Newark, Digikey, and MSC Direct. Digikey sells it for $23, that's significantly better than 23 pounds...
The Aquadag approach looks interesting, but that may not be as reliable. That seems to be a conductive coating intended for rigid objects like CRTs, as opposed to a substance intended to repair rubber keypads.
So if my graphite cure doesn't last, it sounds like the Chemtronics products is the next answer.
