I have to fix a slightly very stupid mistake that I've made.

I'm trying to recreate the conductive lines of a membrane keyboard, unfortunately after trying to unglue them they got ripped off, I've painted 2 coats but it I'm receiving no signs of life from it.

Is Liquidwire the wrong paint for the job? Maybe the circuit lines ar too long to fix? Should I try copper or silver paint?

I've read online that shaking the pain is not enough and that I should also stirr it.

I would suggest soldering on thin wires, even a bit of copper is going to be orders of magnitude more conductive.
- Don't think I can solder on plastic, plus it would create new thickness and I don't think that would help some sandwiched membranes, but I'm going for double sided copper tape, that should help I hope.
