I think if you can get some ink out there it would be interesting to see  
if it forms a sheet on the PCB or if it beads up. You'll also be able to  
see how it holds up in the etchant.

I would also be highly interested in a CuCl test with this (and the other)  
ink, because CuCl can be more agressive than FeCl, especially if run with  
a high HCl molarity (but that can be left down if needed), but i don't  
think you use CuCl.

Without a printer those tests will of course be limited, but i would still  
be curious enough to try.
