I was looking for a way to prevent my new 2017 Mustang from rusting. I live in Canada and here we use salt in winter. I asked a lot of people how I can protect it, and each one says something different. The dealership wants to sell me an overpriced rust proofing kit and I don't think it is my best option.
My options are:
Keeping the vehicle covered outside, maybe do an oil rustproofing.
Renting a covered heated garage. If so, I already used my car over salt so should I wash it before doing so?
Installing winter tires and use it as normal; maybe cold weather and ice will prevent rust from forming.
