11662]600 mile z both front fog lights wax, looks like from the factory someone waxed them and didnt wipe them off, this is in the sealed part, anybody ever see this? guess the only way to remove the wax is to replace the part?

My bet is that the front bumper has been cleaned or even painted and someone rubbed the lens with paint thinner.

its internal not external(sealed), it doesnt look melted from a form of liquid, its wax old fashion wax that was put on when the outer shell wasnt installed yet,then the 2 parts married from the vendor that made these for gm, only i would get this weird stuff
