500SE AMG, E350 4matic, GL 450
It looks like I am going to have to use the 300SEL next winter. I was wondering how those of you in the colder states deal with the salt and the rust that goes with it. I realize a regular run through the car wash will make a world of difference, but is there anything else? It seems like I saw something on 3M making a covering/coating for the car to stop rust. Anyone know anything about this?
