there was someone asking for "i want to know about pcb cnc mill making".

OK, how about this: does anyone in California know of a masking product I
can get here for chemical etching? I have the Chicken Shak (oops - Radio
Shak) kit, but I am using sheet brass and have had no luck with the
transferring of toner from a laser print-out. Unfortunately, I can't find a
California-friendly product to coat the brass to make a developed mask from
an overhead printout.
Thanks
