You can get conductive paint to repair breaks in the demister tracks.

Maplin sell it.

had problem with my demister ...was the connector block in the boot (connection burnt out)

look in the boot ..on the left hand side behind the carpet above/near the left hand side rear tyre ...there is a connector block with a series of wires going into it , open up the block and see which ones are burnt out , cut both wires from either side of the connector and rewire it into another block or directly onto each other , demister should now work fine
