Need to bleed a double radiator, installed July 2000. The front bleeder
is fine, but the rear one is rock solid. Tried WD40, though I use a
brass key it has rounded the valve head before turning. Tried tapping
with a hammer, also managed to cut a rather poor slot in it but still
can't shift it. The big problem is having so little room to work between
the two panels. any ideas please, all welcomed? At the moment it is
starting to look as though I will have to replace an otherwise perfectly
good radiator.

If it's a removable valve assembly, a proper key will fit over the bleed
valve and allow removal of the assembly.

If it's fitted to the rad, drain it down and use a small blowlamp to heat
the valve - heat will loosen most things. Protect the rad finish with damp
rags, etc. A hot air paint stripper might also work.

or use a soldering iron or hot poker pressed directly onto the bleed
screw to minimise the collateral damage.
