guys, u might use autosol to make it shine, but it wont last long, the plastic that were rubbed off will return to yellowish even sooner than the first time in oem condition...the tiny scratch and holes on the plastic will catch the dust and the surface area become bigger.
the method we used to restore the heaadlamp is to scrap off the yellowish then we apply chemical on the surface to seal the tiny holes and ur plastic headlamp cover to something else, so it wont oxidized and weatherized so fast
