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.

Unfortunately the shipping fees would kill me since I'm in Europe, I really wish I could buy a new membrane but it seems like I need to do the repair myself.

Would copper tape suffice as a low resistance trace?

Worth trying. It's already broken, you can't really make it much worse. It'd probably work, and worst case you're back where you started & paying for expensive shipping.
