My husband has spent 40 years restoring/detailing show cars. All paints and sap/pitch are different but his go to method is rubbing alcohol on a micro fiber towel. Hold it on the spot for 5-10 seconds until you feel it start to soften then rub off. As I'm typing this he is removing sap from a customers black truck that owner scratched the heck out of trying to remove the sap. Try it on inconspicuos spot first to make sure it works with your paint.
