Homebrew PCBs

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
