Every one is giving the best solutions that good. Well to add on a bit, as its my work, u need to Wet sand it with a 1000 GRIFT sand paper Dipped in plain water but since the Sand paper is new, dont apply too much pressure on the paper when rubbing otherwise u will spoil the paint on other sides aswell. Make sure u keep applying water after every 20 Sec's. When the Lines begin to go then wash it with clean water & apply Rubbing compound on it with a Fliss soft Yellow or orange cloth. Make sure u rub it as hard as u can. Then use the other side of the cloth to wipe it off. Apply a good waxing polish & u are done. Best of luck. As for the Dent if any just push it out with ur bear hands placed inside.
