So I just got my car shipped cross country and when I picked it up I noticed the car above it on the truck had been leaking oil all over the paint for 3000 miles! Most of it came off with just soap and water but some of the more baked on areas are giving me problems. What can I use to get this stuff off that's safe on the paint? I was going to try simple green, but I wanted to make sure it was safe to use on the paint before I found out the hard way it isn't.

 

nu finish i used that on my car and it took it right off
