    Salt water and chemicals act as an electrolyte between dissimilar metals and can start a strong corrosive action over a short period of time. Maule makes every effort to sepa- rate dissimilar metals with primers and coatings during manufacture, but there are some loca- tions (such as rivets in wing skins) where this is impossible.
