Finally, a question for the electronics experts: in these power supplies there are places where a sort of 'kit' (glue? sealant?) is used where wires meet a PCB. I guess it's to give some mechanical support but considering the voltages it better be non-conductive. To the left you see what's left of it in a ~ 1990 vintage PowerOne SPM5 from an SGI. To the right what you find in a generic SPM5 unit from around 2001. The material from the older unit looks quite tired. It crumbles when put in the ultrasonic cleaner (with soapy water ;-) ).



Any idea what I should use to replace it? It should remain somewhat flexible/rubbery. Ideally something that I can order in smaller quantities because I imagine it doesn't last once you open it.
