Pridley,
I am wrong enough times that you should check this, and Tim is right 93% of the time (higher on some technical issues), but I'd add, if you let WD40 sit on rubber for a week, it might ruin it. Also the smell tends to persist on the interior. Maybe only gasoline breaks rubber down like that, but perhaps a silicone spray may be safer. Silicone would just loosen it up a bit by being slippery. WD40 would work on the rust. The inside edges of the moulding do rust from condensation or moisture from a leaky window. It bonds somehow with the rubber when it's dried out. As an alternative, check it every day to see if it's loose yet.
