New Toyota Corolla

Got a new Toyota Corolla. Within 3 days, I see a small liquid or dirt or paint kind of mild thick layer on a door.
Not sure if this is something related to paint or something else.
Please provide ur thoughts.

Leave as is and, get to dealer.

Thanks.
Is there a chance that this is a tree sap ?

You could clean it yourself and monitor it.

If it is outside the vehicle, then could outside source....
