    Aluminum Ships, Boats and outboard motors use an "anode". You may like to try that? They are really for salt water which causes electrolysis like other metals can. Electrolysis and galvanic corrosion give me the shivers.

    This type of thing. It is cheap to try.

    What's the application?
    An alloy bullbar can be protected by polishing, the corrosion can be buffed to a mirror finish that protects the parent metal.
    Engine or cooling system components can be protected chemically with proprietary coolants. Town water with its clorine can be catastrophic to aluminum.
    If you don't like trucks, stop buying stuff.

    Don't know if it's part of your application, but black polyurethane sealant will corrode aluminium, ANY other colour is fine.
