I recently aquired a 94 D-90 and wanted to get some feed back on it. I saw on the forum that rust is the main culprit on these trucks and mine has more than some unfortunately. Can anyone recommend some sort of blanket treatment for the undercarriage that will stop/inhibit rust?
Heat bypass lever only seems to run on defrost-not to floorboard as I would assume it's supposed to do when in lower position?
Also the fiberglass top is badly sunbaked and I've got mixed reviews from detailers on what I can do to condition it?
Does anyone know of any D-90 groups/clubs in CO?

Thanks-
