Coupe GT Digital Dash Repair

[80q]

The contact points for one of the connectors for my digital dash are worn away in a few spots which has been causing intermittent problems with my tachometer display.

There are some small breaks in what is some sort of conductive material applied to plastic.

I have done some testing with Permatex Quick Grid -- it is a rear window defogger repair kit:

This seems like it will do the trick, but before I go ahead I wanted to know if anyone has any BTDT advice for me.

Thank you.
