Risk of future rust with sports package? Or better protect?

[PhevWestNorway]

Is there higher risk of future rust with sports package?
Or better protection?

Sport package consists after what I see plastic covers in the wheel arches and along the sides.
How is these attached - and is there added some extra rust protection underneath?
This might give an increased risk for future rust under the covers when salt and dirt settles during winter?
In the "old days" there were often rust behind these covers - is this history and if so why?

Or is it an advantage with such additional protection against spills / splashes from the tires?

In Sweden Mitsubishi sends all new Outlander for extra rust protection to external company, so they are not 100% convinced of the factory rust protection, how about in Norway?

Following an excessively close encounter with a refuse bin that resulted in a buckled front wing, I was surprised at just how thin the body skin material really is - more like a tin can than a car body! Get all the protection you can!

The cars gets additional protection upon arrival in Norway.
But it is only a superficial treatment on visible places.
Perhaps it is necessary to have a proper treatment where things are dismantled.
