Homebrew PCBs

Many years ago I used to draw traces with conductive silver paint using an
HP plotter.  The first try was a disaster, the ink solvent dissolved the
plastic plotter pen.
I made a brass plotter pen for the HP plotter and it worked fine.  I heat
cured the ink after it first dried.

Here's a link to a Master-Bond pure silver conductive adhesive. I'm 
trying to get some info on it, but it appears to be a one part epoxy 
(no mixing) that is heat cured. It can be thinned with acetone. I'm 
thinking I could "draw" the circuit with my cnc router, then stick 
the components on the epoxy, the pop it into the oven to cure. Or, 
just cure the epoxy then solder the components.
Any thoughts?
