I just use antiseize compound where I think there might be a problem between say a steel bolt/stud and aluminum. Otherwise, I don't get concerned, don't consider it a problem in regions of the country where they don't use salt worth talking about. It takes salty water to complete the circuit so to speak. Many salts, such as sodium chloride, behave as electrolytes when dissolved in water. A dry joint won't have that.
And, pure water will not behave as an electrolyte, thus with only slightly acidic rain we have here in this area, not much goes on even when it rains all the time, lol. Moss/mold is more the problem. I do go through and spray WD-40 around, just in general, and wipe it down, just to keep surfaces from showing any degradation as well (probably doesn't do much, but it looks ok afterward).
Because your area has a fair amount of irrigation and hot weather, the soils do become acidic (some southern areas of the Central Valley are quite acidic and so contaminated with salts, many plants won't grow), and rain will cause runoff to be fairly acidic, so I've read. So, just use plenty of antiseize, just to be safe (of course it is not like the Midwest or east coast, where the ph of rain and soil is rather high in comparison, and tons of salt are used on the roads).
