I purchased my new 2017 GLC300 about 3 weeks ago. Yesterday I noticed what appears to be rust near the door handle on the rear passenger door. See attached photos.

I'm taking the car into the dealership for service and a thorough rust inspection this week. Is this something I should be worried about? Any advice on how to ensure the service department addresses this issue correctly?

Doubt that is rust. Looks like it would wipe clean.

Don't believe that's rust but a corrosion preventative material.

Last summer as the outside air temperature increased I noticed a similar looking material dripping from both front door drains. It took two attempts to remove it. After which there was no recurrence.

That is not rust. Agree with Larry. I had it on my car also. It was for corrosion.
