My wife’s Explorer is kind of a mess. After running it through the touchless car wash yesterday I clay barred the bugs off the front of it in preparation for wax. On the hood there is some nastiness that didn’t come off with the clay bar. Looks to be tree sap, bird crap and/or bug crap. There are also tiny specks of rust on rear and a few here and there on the lower door panels. I’m assuming the rust specks are something on the surface of the paint and not actual body rust. How do I get that nastiness off?
