I have a 55 year old door chime clock and the board has carbon arcs which is
causing a short. I have seen boards with this problem before and they were
repaired using some type of filler. What is used?

Thank you for your help

This doesn't sound right, you can't arc with 24 volts. But, if it fact
it has happened, I'd recommend using a dremel to grind out the bad
parts of the board, and spray with a insulating coating, or even
fingernail polish.
