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.

With all the proper tools and materials, I am a professional, capable of soldering traces about as thin as a human hair.

And when it comes to carbon traces, we absolutely did use conductive paint to fix damaged traces. But now I'm more into automotive repair and just don't happen to have any conductive paint in my home electronics repair materials.

All I was wanting was a good homebrew solution to properly patch a ~3mm damaged section of carbon trace, not some hack solution that'll just end up wearing loose and having a bad connection within a few months of gameplay.

So I do not find your answer helpful nor professional.
