I was at a machine shop here in Jakarta several weeks ago and they do selective plating etc for Aircraft parts, they had also repaired an Engine Block in a camshaft bore using a Coloidal Copper solution (IIRC) applied with Electrolysis,
my first thought was to use this solution to plate via holes also, but of course the hole must be conductive for this to work so maybe the conductive silver pen will have to be used first to get the process working. I dont know about the price but looking at the amount they chew through 1liter would last me a long time if it worked ok.

And more importantly, who is gonna pay for it?
The starting set of chemicals is so expensive i can have the boards done
professionally.
