From my experience with wheels with clearcoat, I'd say stay away from them like the plague. I've never seen a set last more than 1 or 2 years if there is anything resembling salt on the roads where they're used. The pic of mine in my sig is of a set of AmericanRacing wheels that were clearcoated when new (most of that crap has flaked/worn/whatever off and looks really bad now).
I'm getting new wheels sometime soon, and they will not be clearcoated. Probably not such an issue if you never see salt, but around here even though we really only get a couple of snows a year, they just won't last long.
