Interesting coments about aluminum and SS. They must use a different alloy in aircraft aluminum. When I had my boat I was told that the aluminum alloy used in it (a mid-1950's vintage Loan Star cabin cruiser) had an electro valence similar to SS. I promptly changed out all my fasteners and other mild steel parts to SS (I also tried as best as possible to insulate the metals from each other) anyhow it pretty much solved my corrosion problems (like having mild steel parts completely ruined by rust in a matter of months).
One interesting item, the previous owner had installed a brass self bailer in the hull, when I took the bailer out I had to put a 1 foot square aluminum patch over the area because corrosion had thinned the aluminum hull so badly.
