Thanks

Smash the glass out - seriously, try to do it in large pieces to make
it easier to handle, and once it's out, you've got an edge to work
with. An old wood chisel is about best for this job

Agreed - and to add to Phil L's advice, use gloves and googles [1] and put a
large dustsheet down to catch the broken shards, and empty this straight
into the wheelie bin when done.

As for preventing damage to the frame - almost impossible with hard putty
that's stuck well into the frame. When used to do the job, I simply took my
time and filled in any damage when applying and finishing the putty, and
then touched up the paintwork.

and cuts to the fingers are bloody painful - believe me!
