Hi Clark,
I haven't yet tried the process with the "China" paper, whatever it
is... I did get some to try when I have time (which won't be soon, due
to other projects). It appears somewhat similar to the backing on
contact paper.
I have on occasion used plastic model paint to touchup pinholes if they
apear too big for the green film to cover... many decisions are
variable based on the overall size and geometry of the parts to be
etched. The parts I was working with were small, roughly 1/4x1/2 inch or
so in size with holes and tabs... With care I held to a couple of
thousanths overall tolerance. Its been a few years now since I've done
anything along these lines...
Roger
