all this talk about rust proofing in this newsgroup had me thinking. 1995 honda del sol vtec. my baby, the paint is wonderful. underbody is in pretty good shape according to the mechanics that have seen it on lifts. Should Krown or RustCheck be something to consider for the upcoming winter season? I will drive it through winter again. i'm talking about the oil, or wax or whatever is recommended for the underbody.
