Homebrew PCBs

This is starting to sound like bad news to me :-(  It is odd that I 
got the durabrite ink to hold up to etching and such by just 
applying it to "stock fresh" copper.  However, brushing these inks 
is a world apart from having them sprayed on via the printer.  

I sure hope you get some success soon, there are a handful of us out 
here that have already got printers and/or ink waiting in hopes this 
will work :-|

I have the MIS inks here but the printer is not ready yet. I might 
still try a couple things later today.  Perhaps I could put the ink 
in an air brush or something and spray it on the PCB material for 
testing ?
