WHAT? HELP!!
You say all my humongous efforts are for nought?
I fear i must despair here, no working glue, no good for chemicals, i can
just about throw my newly bought lexan away.
Any idea what will happen to the lexan in CuCl?
I'm at my wits end with that stupid sprayer. I have wasted hours (and
money!) and i'm still at square one (actually behind it really..).
I want(-ed) a transparent tank to see things clearly, especially spray
pattern and such.
I really needed that unexpected success with the silicone paper today,
otherwise i'd go pretty mad pretty soon.
Oh well, i'll sleep over it (again), i'm sure things look just as bad
tomorrow.
