Homebrew PCBs

Although I'm not interested in this technology, I'd thought I'd drop a
teaser
Minwax polycrylic is a water soluble polymer, It's thin-able with water, and
dries to a chemically resistant and VERY hard surface.
The only possible problems I see with it as an etch resist, are 1: it may
not adhere to copper, and two if it does, you might not ever get it off.
