Wht if internal car temps change quickly from warm, then to cool humid air? Cool air can't hold as much moisture, but it could still be present as condensation. That's why we sometimes must quickly brief/ 'do' Cat II or III approaches.
A guy told me that his rifle had sudden corrosion on it after one night because of warm quickly into cool temps with ambient moisture.
Dumb question, but am retiring in three Weeks and have nothing to lose.
