You don't want to be opening up your laptop and spraying CBs. The system
will overheat. Buy a laptop that's designed for the marine environment
(rugged) or not use it as a primary device should the one you have fail
due to corrosion. I've known people to go for a long time with a regular
one without any problems. Probably one big problem is damage due to it
not being secured when the boat is in a seaway.

I dont see too much relation between spraying the PCB with something, and
heat transfer. I was involved with PCB repair for 3 years, and learned a
bit about PCB production in that time. Most PCB's have a waterwash as
part of their production to help clear acids from soldering (the water is
treated) and are then sprayed with some from of antistatic or protection
spray, its the stuff that gives the board a greenish tinge. I still dont
see any reason that an additonal spraying of an anti corrosion spray over
the top would hurt.

Well, you asked about spraying them with "anything," and it seemed like you
didn't have much experience with this sort of thing, so I answered on the
safe side. If you spray the inside of your computer with stuff that will
insulate the PCB, you're going to increase heat retention on the board.
There's a big difference between antistatic spray and coating the PCB with a
think layer of stuff. You'll also void whatever warranty you might be able
to claim if there's a problem.

If you know more about it, then why did you ask?
