Hi All,

With regard to chemical etching of boards, what chemicals or materials
are good for resist? I know there are resist pens, but I am unsure of
what the "Ink" is actually made of. I also know that toner, which is
primarily plastic, works as a resist.

Just working on some ideas for alternative ways to apply resist.
