Homebrew PCBs

Unfortunately I think you're right. I expected a material labelled 
as acid resistant to be resistant enough for etchant. As I can't do 
without screws I have to try and get plastic screws, but chances 
that I can buy PP, PE or PVC ones are small, these are usually made 
from PA which is again only halfways resistant.

Regards
Martin
