Sort of been there, worked for an oil shipping firm for years, based on the waterfront, Tugs......
Thinned out Automotive Epoxy paint would do motherboards, switch PCB boards but there are too many parts which you can not spray such as switch ports, com ports, PS2 ports. Any spray capable of coating electronic parts, will also pickup salt and dust particles.
You Idea of getting an enclosure is good, for modifications...
The easiest solution would be to have a closed system enclosure, with an A/C unit.....
Use a "split" air conditioner, with the heat exchanger unit mounted within a hermetically sealed computer enclosure. Even if salt laden air is introduced into the enclosure during maintenance, the heat exchanger will condense the moisture from the air, which would remove almost all salt from the air, then the interior of the enclosure would have little moisture to react with any salt particles remaining. There would be an issue with the longevity of the condenser coil.This would also condense dust from the air.
Not as good, more complicated but would do the job......
Air sent through a HEPA filter, followed by a dehumidifier, then into the enclosure.
The HEPA will remove salt particles not dissolved in water particles in the air, the dehumidifier will remove salt saturated water particles in the air, and salt particles suspend in the air too small for the HEPA to pickup. It would be important to get a dehumidifier large enough to treat all the air going to the enclosure. If it does not condense all the water from the air, some salt laden air will get to the enclosure.
