I lease a hangar at KOLM. This is in the Pacific Northwest and hence is very damp in the winter. I don't think that I can modify the hangar to make it more weatherproof and so I wonder what you all recommend as far as further protection of the airplane engine and interior. I've installed one of those marine fans to keep air circulating inside the plane. I've heard that some people recommend an engine dehumidifier be used as well if you are not flying very often (sounds like a gizmo that you insert into the oil filler that blows in dry air to prevent corrosion). Any thoughts? Any other advice on keeping your plane free of mildew and rust during the rainy season?
