problem with shiny wheels is there is no easy answer...
bare ally tarnishes real quick, and in winter corrodes easily
chrome falls off if someone walks past with a bag of salty chips
clearcoated ally is the toughest shiny finish, but if corrosion begins under the clearcoat they look horrible very quickly.. (it will after a good winter, all it takes is 1 nick in the coating)
the only other options are to keep your old wheels, and switch them in spring / autumn, or to take the car off the road in the salt season..
unfortunaley, bling requires fastidious maintainance, neglect it, and its scrap..
