Replying to Tree sap on cars

i have a massive pine tree that has probably been there since the dawn of time and it always jizzes tree sap onto my car. normally i would just cut the fucker down but its on my neighbours property and they refuse take the bastard down because its been there since they moved in and they watched it grow and gay shit like that (they're like 95 years old).

anyone have any good tricks to getting tree sap off of cars without wrecking the paint job?
