spray laquer, or is there a specific spray on finish to coat the boards?
It's called "Conformal Coating". The proper top-notch stuff we use for IS (intrinsically safe) mining gas monitoring equipment is not cheap. Most larger electronics suppliers will have some sort of aerosol lacquer (ask for Circuit Board Lacquer) for a reasonable price.
