I bought myself one of these new "liquid pencils". It's like a retractable pen, but draws a nice thin (0.4mm or so) line with this "liquid graphite" ink. It erases very nicely, and supposedly becomes permanent after 24 hours. I'm wondering if this pencil mark has enough conductivity to allow me to plate additional copper on lines drawn on a nonconductive surface like fiberglass? http://web.media.mit.edu/~plusea/?p=554 [Non-text portions of this message have been removed]
