It is a difficult and almost impossible task to overcome the physical process of water condensation from the air on the sea coast. Humid air penetrates into all cracks. When humid air cools, water falls in drops on all parts of the metal. It is like morning dew on the grass, it will always be there if there is humid air and coolness. Seal the car, turn on the air conditioner to dry the air and the fan on the battery to drive dry air through the battery case. It is easier to move to the desert, where there is no precipitation 350 days a year.
