Question
What works good for removing tar from car paint?Thanks!

Answer
RANDY,   ARE YOU READY ?
       WD-40. WILL CUT THROUGH THE TAR AND WILL NOT
       HARM THE FINISH. SPRAY AN AMPLE AMOUNT ON THE
       AREA AND LET IT SOAK FOR ABOUT THIRTY (30) OR
       SO MINUTES. THAT SHOULD GIVE THE CHEMICALS TIME
       TO BREAK DOWN THE MOLECULES.
