Yes, to both! Sure, the average humidity is higher here than in many parts of the country, but I don't think it's excessively so. Unprotected steel rusts easily, as it does anywhere. My vehicles last over 20 years with no corrosion evident unless the paint fails, and then you get surface rust. That's correctable if not allowed to progress (like anywhere else). I like to rumage through aircraft salvage yards and have seen a LOT of exposed aluminum. Living in Florida for over 30 years now, I have not found a higher incidence of aircraft corrosion than in most other parts of the country (desert states do seem to be the execption from what I've read). Aircraft that have been based in Florida since new don't seem to develop "frost" (surface corrosion) in the interior skins of wings like they do in northern climes. It's just a theory, but I attribute this to condensation on interior surfaces as the sun melts snow off the wings when conditions are right. Birds under roof don't seem to have as much "frost". I can't prove anything. It's not a scientific study. Just my humble opine.
