Re: aluminum, steel, and rust
Basically you're putting two metals next to each, with touching
using some kind of separator, like maybe silicone, making a electrical
charge much like how your car battery works. Its called electrolysis:

putting tinfoil between two teeth with silver, mercury fillings.

So the question is what can be done to minimize dissimilar metal
electrolysis.
For instance, the soft metal (Magnesium alloy?) used in the typical Jeep
mirror mounts on my half doors has that powdery corrosion UNDER the
paint, I assume this is from electrolysis, the other metal being the
door hinges they were attached to, and the steel bolt/spring assay.
inside the mount.
Obviously steel rust doesn't require dissimilar metal corrosion, just
water and exposed steel. So you can use paint, rubber, or "pansy"
silicone to insulate the steel. But can you do anything for parts that
have dissimilar metal corrosion built in by their nature (i.e. zinc
coated steel spring and carbon steel bolt/nut inside the Magnesium
mirror mount)?

Anti-seize compound. Pretty much stops dissimilar metal corrosion in
its tracks.
Not a cure- all, but if you remove existing corrosion, prime and paint
the affected parts and reassemble using anti-seize on the hardware,
you will be in pretty good shape. Keep the moisture out as much as
possible and keep any drain holes open.
