Question

Answer 1

the military used to coat electronic boards with clear lacquer.

Answer 2

Outdoors is really a bad place for electronics in general.  The really good equipment is weather sealed but consumer grade products are not usually sealed too well. You might try taking the units apart and adding a bit of silicone caulking around everywhere there is a seal to the elements.  You can clean the contacts lightly with a wire brush.

This is great contact cleaner and protector:
