My 2015 mustang has lots of waterspots and what looks like scratches on the headlights. Is there a proper way to clean these headlights to take off the water spots? or should I break out the meguiars plastx? I took some pics of the headlights. Incidentally I have my own spray on clear coat with UV protection if I need to polish my headlights and am forced to apply new clear coat to the headlights, but it's not meguiars clear coat spray.
