Goof off works great, is quick and evaporates pretty quick so it won't sit on the paint (a cheaper alternative to Good Off is simple charcoal bbq lighter fluid, but Goof Off is a little less concentrated so I always stay with the Goof).
Also, anything that takes off the sap, tar, etc. will strip the wax (or whatever surface protectant you have) so plan on reapplying that when totally done.
If you want to talk to your neighbor about alternatives to pine tar dust abatement applicant (besides the fact that if he applied this to a county owned/eased road he is in violation of state rule, as a private party cannot apply dust abatement without a permit), there are lots of options that are cheaper, more effective and don't cause the sticky problem. Examples are lignite (basically coal ash), or PAM (polyacrylamide), are the ones that commonly come to mind, as they get mixed in the tank of a water truck and simply sprayed on the road, the water evaporates and the resultant is a sort of dust compound that promotes the native dust particles to bond to each other without the stick (the suppressants have a slight positive electrical charge and the native fine dust particles have a slight negative charge-it's like Chuck Woolery bringing the two together).
