I have the bottle, i have the x-grooved pen, and i have no useable result.
do not waste your time with it.
the trailing edge of the pen scratches the layer of ink thin, so that the 
etchant
gets through.

also the plotter i have is so slow, i can make 10 TT in the meantime and 
they
are better quality.

NOT WORTH THE TROUBLE is my conclusion.
I know some people use the OHP pens directly in the plotter, which would 
work, but
the line widths (ant the consistency of that) is not what i need.

However it makes a beautiful component legend.
