cheap and easiest was is mineral spirits on a rag. done! I once owned a Suburban and a road worker made me drive through wet tar before the chips were added both sides of my car where covered. I used the risky but effective gallon of gas on a rag. Took it right off. Then washed and waxed and was perfect but did take some time! Warming it up is a good idea. So is the clay bar someone suggested. I just did the entire car yesterday with clay then buffed it all out with a wool pad and Drywash and guard. Some of the tar spots were difficult but not impossible.
