I have noticed that on the very bottom of my front doors there is a slight amount of I think grease. It is also on the back hatch door. I cant see anything under or anywhere else. At first I thought I ran over something but it came back. Any one have any ideas? I noticed it on the back hatch because when it dried it turned to a rust color. It is not alot but enough that I noticed.
