It's Monday... had your coffee yet?

I'm trying to gather together some potential solutions to High Voltage
breaking over and arcing between traces on board. The things I know
contribute to this are things like, too little spacing between traces on the
surface or in the inner layers, sharp points on traces, board cleanliness or
the presence of contaminants between the potential voltages.
It was suggested that conformal coating the boards after a real good
cleaning might improve the insulation resistance between traces, has anyone
done this successfully? Do you have any other ideas short of a re-layout of
the board that could perhaps repair a problem like this?

Any ideas are most appreciated.
