Fine pitch trace repair
Just putting side by side a Scotch for masking.
Remove the adhesive immediately before the conductive ink dries.
And then repeat with the next track. (Wait at least 1 day).

From my own experience, try first on something else.
No way to get that fine a trace without meticulous back taping, which will be a major problem with adjacent traces damaged (tape will lift CW paint).

Due to an unfortuante jab with the head of a screwdriver it looks like I
have at least one, possibly two broken traces on this GPU card....
I keep a length of a scrapped RCA audio patch cord that is made of the thinnest gauge wire I've ever seen. When I repair boards like that, I pre-tin a strand, put a tiny bit of liquid flux over the damaged circuit area, and lay it right down over the break. I use fine pitch jeweler's screwdriver to "guillotine" the wire cleanly off the board. Once all the traces are done, I clean the flux and examine under a microscope.
