> Hi ! I read from an old issue of radio electronics one of the ways they
used shellac in preparing PCB's. They first dyed the stuff so that it would
be visible when applied. Then, they loaded the thing into a technical
drawing pen and used that to directly apply the shellac as an etch resist
onto the blank pcb.

Nail varnish is supposed to work quite well, also.
