I just polished my plastic projector headlamp (angel eyes). What happened actually is my headlamp's clear coat layer started drying up, causing the plastic to look foggy and got flaky effect. Really rough and ugly.
My steps require time and effort but it really works for clear plastic with damaged clear coat.
So what I did is:
Buy 1000 and 1200 grit sandpaper, Mequire plastx and liquid car wax. Cloth and wax sponge also needed.
Get ready a small bucket of water. Dip the sandpaper (1000grit 1st) on the water and sprinkle some water on the headlamp.
Put some liquid car wax on the headlight (start on a small area first) and start sanding the headlight. In between remember to add more wax and water. Also sand diagonally only, don't go vertical then circle. Otherwise it will look messy with many lines in many directions, not good.
Clean the headlight with cloth to see if the layer is removed. Repeat if require but make sure you don't sand too hard or use to much strength.
Once done use 1200 grit sandpaper with water and wax to smoothen the fine lines caused by the sandpaper.
Once done clean the headlight with dry cloth until all wax removed.
You will notice its foggy and blur but don't panic yet.
Now use the sponge and Mequire plastx and apply it on the headlight. Make sure the lamp is dry. This part require some effort. You need to polish it until it becomes shiny. Usually it will only take you 15mins. Don't forget to add more Plastx in between.
Just polish until it is shiny then leave it dry for like 15mins. Use a dry to cloth to wipe the headlight. You can redo this part as many times as you like until you are satisfied.
Next thing you know your headlight is like brand new.
For those with no damage clear coat, sanding is not required. Just use plastx directly. This product really works wonders.
Hope my technique works for your headlamp too. :)
This is after few days when i DIY my headlight.
