SO i was refinishing the front of the S60...too many stone chips, when i decided that i would try redoing the fog lights...they were also stone chipped- pretty badly...they were actually kinda foggy looking....so i wet sanded them with 320 sand paper, dried them off and shot them with the same clear i was using on the car. i was doing a basecoat/ clearcoat system using NAPA paints. I used their best clear which was quite expensive ( like $275 a gallon)...anyways they pretty much looked like new units when i was done. The crummy looking one on the left is the one i was replacing. it was broken in back. the pitted glass is pretty much what the other two looked like.
