I have a white 2008 passion and we have huge pecan trees in our yard. The ripe pecans still in the green casings are dropping and have a yellow greenish liquid/sap/goop and I have been noticing green yellow stains all over my car! Has anyone else had this problem? Did the stain come off? What do I use!! I've used everything wd40, windex, goo be gone, turtle wax, turtle was bug and sap remover! Please help!!
