I messed up a couple of traces on a Ducky board I was taking some bad switches off, after much looking and finally thinking I would have to use wire and go across the bad spots I found a trace repair liquid that seems to work very well, at least my meter says it works. I'm still waiting for the new switches to arrive to know for sure but here is the product if anyone wants to try it or has tried it let me know how it worked for you and if it holds solder, thats still the big question I have.
