Does anyone have any advice on how to make homemade conductive paint to fix a cracked carbon trace in a game controller? (lemmy.world)

It's the trace going towards the mode button, so I'm pretty sure resistance won't exactly be critical over a ~3mm gap, as long as it recognizes when the plunger button is pressed down.

Update: Nope, Pepto Bismol is useless as any sort of substitute for conductive paint.

Yes, Pepto contains bismuth, a conductive metal. But it also contains some mild acid and whatever other ingredients too.

While still wet, it's lightly conductive, but once it dries, it's about as good as an insulator.
