The corrosion may not be from electrolysis. Please remember that aluminum
(aluminium) is very reactive. It could be a reaction from chemicals in the
air from industry. Is it present on the inside as well as the outside? Most
people that own aluminum boats paint them with 2 part polyurethane and be
done with the problem. If you elect to go that way, be sure to use an
etching primer first.

Most people with aluminum boats leave them unpainted.
