I am adding late to this conversation, but I also owned a Smoky Topaz Lexus LX 470 that had severe paint fading and oxidation. I have owned 4 other Lexus vehicles and treat them all the same: garage kept and cleaned weekly. I have never had any paint problems with any of the others, so it seems that this is a paint problem with this model, year, and paint color....too bad as it was originally a beautiful shade....
