Last summer I bought my 2004 Lexus IS 300 from a Florida dealership, shipped in to my home in Illinois, and managed to keep from driving it all last winter. It looks as if I'm going to be forced to drive it this winter and expose it to the road salt which destroys cars in the midwest. Does anyone have any experience with any shops that apply undercoatings, rustproof, (whatever you want to call it) cars to help prevent or at least slow the onset of rust? Any suggestions would be very much appreciated! Thanks.
