Thanks for that, this should be fresh as I just brought it but who knows how
long it's been sitting on RS's shelf.
Another thing I thought of is that it had not dried properly.
I have another set of practice boards curing overnight that I will play with

Is there a better etchant than Ferric Chloride?
Will I ever get some sleep?
Thanks for the help.
Daryl.
