Homebrew PCBs

That is just so strange.  Volkan is indeed demonstrating that he is 
a crafty fellow!  Brake fluid, what the heck!  For a wetting agent, 
that would have been the last thing I would have tried.

As another possiblity for a wetting agent, if someone out there is 
trying this and wears contact lenses, I believe one of the chemicals 
used to clean or rinse them is a wetting agent.  It's been nearly 40 
years since I tried wearing contacts and for some reason I 
remembered this information about them.

Brake fluid - I am going to be pondering that one for a while!
