tree sap

hey im just wondering, what u guys might use if u ever get things such as tree sap on ur paint that has already hardened and cant seem to get off, i dont wanna damage paint and not sure what product to use that wont harm the paint also, any ideas?

if u go to a ppg paint store u can buy a bottle liquid luster it is pink.That will take anything off with out damaging your paint it is awsome stuff you might be able to get it a oriellys at there paint store
