I have a 15 year old ski boat and the original cover for it.  When I have the cover on it and it rains, the boat will get mildew on the seats and interior.  Is this a normal problem and how do you correct it or what should I do.  I also park it under a car port, but dust, leaves, and critters can still get in it.
