I have a tiny PCB that I've been working on and off of for a while now. I received it with leaking batteries, and it had corroded some of the traces off the board. Most recently, I tried redrawing the burnt traces with conductive paint, but to no avail. I actually popped batteries in it last night and had activity for the first time ever, though it was short. I then scraped off the paint and decided it might be time to try a jumper wire.
My question is: there used to be a trace pad that completely came off the board, do I need to worry about that? Is it possible to skip the pad entirely and make a bridge between the two sections of trace?

The two points I would bridge
I'm familiar with soldering, but not with specifically making a jumper wire. Mostly I'm trying to find the right kind of wire to do it with and where to purchase it.

You can use a thin single core wire (which you can easily form into any shape) and solder it directly to the smt resistor from where the trace begins. Strip the wire slightly and make a loop where you want the pad, and complete the trace by soldering it to the via on the right. Choose a thickness of the wire that you can insert into the via. Not sure about your soldering skills, but shouldn't be much difficult.
