if its just the clear, then you could prolly get away with wet sanding with a fine sand paper (VERY fine) and applying some type of clear coat from a paint place, that comes in a small can (try home depot), thats what i'd do 
REAL fine.. and read up on wet sanding.
Like someone said earlier, as long as the finish is okay you can re-clear them. Look long and hard at the chemicals and methods you use to clean your wheels. ... anything you wouldnt do to the paint of your car you should never do to your clear coated wheels!!!
