How to remove oil based paint overspray from an automobile paint finish

I work for an industrial maintenance company who specializes in epoxy floor installations, primary and secondary containment, confined space entry for industrial coating applications, etc. On a project last week, we were spraying an afterburner w/ industrial oil base enamel. Unfortunately, the overspray got on my truck, (my mistake I know better.) Other then using a strong solvent such as Xylene ⇦ on eBay or Amazon [affil link] , which will take it off, is there any thing else I can use to remove it that's not as hot of a solvent. The Xylene does take off the over spray, but also removes some of the finish, I tried it.Finally, I realize I will most likely have to buff the truck after the overspray is removed.

Thanks,

If the coating has not cured, isopropyl alcohol may work. It will not harm the automotive finish.
