ok i have a 2009 cadillac DTS and im wondering how long will it take for rust to form because i live in canada and its winter most of the time and there is salt on the roads and also how many times should i wash it in a week?
Well--take the time to read the owners manual--it has a page about CARE FOR THE EXTERIOR AND INTERIOR. That should answer the questions. How many rusty Cadillacs do you see around your area?? Ask another owner if HE has rust.
