Conformal coating is the stuff that's used for commercial protection
of PCBs. But $15-25 per can, so a lot more than regular paint. Still
smells like complete crap when you solder through it too. I seem to
recall mention of a solder through type, that wasn't so bad for rework,
but it's been a long time and I have no specifics since I never used it.
Paints/laquer etc may absorb moisture, and may become conductive etc
over time. Long as your stuff isn't too critical, it shouldn't matter
much. I've painted more than a few boards with just straight black
paint to cover them up, and no real ill effects, but no high gain amps
etc either.. Maybe test your paint though, some are noticably more
conductive than others right out of the can.
