It is this film that is the main source of aluminum corrosion protection. An example of the safe use of stainless steel fasteners with aluminum would be where stainless steel bolts are used to secure aluminum roadway. Aluminum oxidation happens faster than that of steel, because aluminum has a really strong affinity for oxygen. Nice work, you have made an observation that the average boater would never have made.
