We sell use a conductive pen that we use to connect gold contacts 
together for plating repairs.  We have never used them for 
repairs.  We repair the traces using copper circuit track 
material. The trace material is available in many different 
widths. We then over bond the trace with colored epoxy.  I have a 
procedure if you are interested. Another method is welding, but it 
tends to be more difficult.  Both Methods are recomended by the 
IPC.
