Windscreen heater wires - repair / overhaul

Rear windscreen out - I've little idea whether the rear windscreen demister works partially or even at all but the wires appear to be in a complete state. Probably the original one of 50 years. Is there hope to salvage this, or is it just a case if scrub it all off and start over? Anyone with experience? Can you get new wires? Or better just to get new glass?

Very doubtful these would work.

You can (used to be able to) buy electrical paint to repair the tracks. I had limited success in the 80´s

My car had repairs conducted in the electroconductive paint but it didn’t work. I bought a new screen from Porsche.

Good point. I never look out of the back window anyway. I already know all the other drivers are rapidly disappearing out of view.

Perhaps some of the conductors might be OK/work - I think they are all connected in parallel, in two sets I think.
