Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

I saw a site a while back where a guy was using a PCB sensitizing
spray in a can. It was from Europe...I can't remember what it was
called...GPC or something. You just sprayed it onto a board,
exposed, developed and etched. I looked and looked and even emailed
a bunch of companies to find it, but never did. I am told it is
fairly hard to use, as it is said to be tricky to get the right
uniform thickness of the stuff on boards.
I'd still like to try it though. Does anyone know what some of
these products are called and/or where to find them in the US?
