Hello Jack,

i'd say if you havent cut a trace _inside_ the panel, but only
one or some on the surface, those are probably repairable.
The shorter ones can be just soldered together with a precision
soldering iron. If longer parts of a trace are rendered
unusable, it can be patched with a thin patch wire. So if
you dont have the proper tools, chemicals, and knowledge to
do this yourself maybe ask someone who does, but i dont think
you really have to throw away your Multia...

BTW, its _very_ unfortunate that the Multia FAQ mentions this
method, which is probably more dangerous than any other coming
to my mind right now...
