See section 4.2.4 (part 3 of PDF documents) in the IPC board repair manual in my signature. It all depends on the trace size.

What I did was just order a bunch of solid core copper insulated wire from Amazon, ranging from 40awg to 30awg.

I have a few motherboards that I got in a scrap lot that have some damaged traces so I need to finally buy some wire for repairs.

From what I am seeing in searches, it sounds like 30awg kylar insulated wire is good.
What about solderable magnet wire? I am seeing that mentioned as well.
Some of these traces are very thin so I would need to stagger the repairs or run a longer wire from where the trace ends.. probably a better idea from what I can tell.
Any pointers from those who have done proper bodge wires before?

Magnet wire is just enameled copper so for short straight runs along the old trace will work good but if you cross other traces then no (always a chance of shorts, is why the old guys used plastic coated wire for RMA fixes).
Using insulated small gauge with plastic or nylon coating would be be best.
Good info wiretap !

Mostly using 30AWG Kynar insulated wire for that kind of jobs, got this 100m roll I never used up during my console modding days. It's usually a good choice for repairing signal traces. For the few cases where it's too coarse, I simply use a strand from some other wire.

For power distribution traces, I just pick anything with a larger cross section area than the trace to be repaired. The single stranded wires from ethernet installation cables are often useful for this.
