Hi, new here. My dad has a 2014 Panamera 4, loves the car. It's only got 9600 miles on it, so it's practically brand new. We live in the "salt belt," so there's a lot of salt everywhere on the roads and all of our cars are becoming salt magnets. I noticed on the salty tailpipes of the Panamera that there was a little bit of rust. How should this be dealt with? It doesn't seem to rub off. I'm going to wash it well later, but I really don't think it'll come off too easily. Should my dad take a trip to the dealer? I'll include a picture of the left and right tailpipes. Thanks in advance.
