Homebrew PCBs

Particularly to Adam for the suggestion of the multi-exposure board 
idea. Did that and now I've just finished my third perfect board (6 
minutes is the best for my setup). These boards have traces down to 
10 mil all spaced 25 mil between centers and no shorts or opens. 
Hell, I even have traces sneaking between IC Pins without shorts and 
I though that'd be impossible.

Now I'm looking at Dielectric sprays. So far I've only seen two 
types. Silicon and .. uh oh, brain spasm... can't remember the name. 
Its like a varnish or something. Anyway, what are each better at? 
I'm looking at deploying some boards in a swimming pool, hot, humid 
and lots of trichloromines floating around - want to protect that 
copper! I also have an un-heated shed that needs a board. Being on 
the west coast of canada that means from just below freezing up to 
100F in the shed. Quite humid most of the year too.

Any thoughts?

Ok ok, not *IN* the pool, just in the building that HAS the pool in 
it :D
