Depends upon the size of the sap. The sap that comes off the trees here is usually very tiny droplets and they always wash off with water. Clay bar should work just fine, but be sure to use a lot of detailing spray to keep the bar from scratching the paint (I use Meguiar's Final Inspection but any detailing spray will suffice).
Also, fold the "dirty" surface of the bar in on itself a few times (kind of like kneading dough) to give you a clean surface to work with.
