RW, best thing to do at this point is dive in a little bit deeper.
All you lack at this point is the re-plate trick.
After drilling, double sided boards are re-plated with copper.
That builds up the surface a bit thicker, but mainly plated the through holes with copper.
Then they will take solder.
But without replating they will have to be "wired" one at a time.
eyelets are quicker and easier. But not exactly cheap!
There are sites about that advocate drilling all the holes and the with the aid of carbon loaded ink the holes could get plated, then the track layout could be processed.
The brew of chemicals that were mentioned would probably bring an armed response team to my door. When I was a kid, you could get all sorts of stuff but not now.
I have completed the CPLD board, with its parallel port JTAG bits and it does work. With this confidence I will have a go at 0.4mm for the Prop II, unless they make me a nice DIP128 one :-)
