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.
