i've seen aluminum grow a white coating over it in patches. it was some sort
of oxidization which is what rust is(joining of oxygen to metal i've been
told). may have just been the quality of the aluminum. when i am working
with aluminum conductors (i'm an industrial electrician) we coat the exposed
aluminum with a product called noalox. it stops the production of the
aforementioned white coating which has a high resistance and can cause
aluminum electrical connections to catch fire.
hope this helps.
