aluminum does corrode into alike a green/white kinda color.
i drove around my G throughout the winter last year in heavy salt myself in chicago, but no rust. you sure it's rust and not a clump of brake dust contamination? if it's brake dust, use some cleaner wax. i'm sure you already know this, but make sure to wax your wheels with decent wax before the first snow fall. meguires cleaner wax tends to bond to the surface longer than regular goldclass wax for some reason.
if you use sand paper, touch up with clearcoat afterwards.
yeh, just go to the store like kragan or autozone and ask the clerk to list up the KN filter for the 99+ . they all fit, got one on my 01'.
