I have used 70% Isopropyl Alcohol to readily remove pine tree sap on another vehicle which sits outside. Spray the sap spot, then wait about a minute for it to work. If it is sap, it'll begin to "melt" with a definite line drooling from the sap spot. Wipe with appropriate non-abrasive towel/microfiber towel. For big sap spots, it may take a few repeats to completely remove the sap. Alcohol evaporates fairly quickly, so sometimes I'll have to spray the spot a second time before wiping to keep the paint wet.
