Hello just received a 2024 Ford edge, I know its talked about on other forms, but I was looking into rust proofing here in Canada (Krown, Rust Check, Corrosion free). I asked 2 separate dealers, and a family member who works at one of these dealers and they said that the rustproofing could void the warranty on certain parts if they are contaminated by oil. I tried to contact Ford directly but got the standard answer about making modifications. Any one have any insight to this?
