Yikes?   I do this for TV/Projector, PC boards all the times on 
tracks that comes off for any reason, bridge cracked PCB etc.   I 
scrape off mask and polish it with eraser rod and lay sized and cut 
to length if needed pre-shaped to follow the bends in the trace and 
solder.

This repair method is stronger.
