How to use Liquidwire (conductive paint) (imgur.com)

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 was thinking about using thin copper tape, it's cheap and it should be better that some graphite ink I hope,

Definitely better conduction than the paint. Just make sure that the tape isn't coated where it has to make a connection to the pads.
