Hi,I was told by a detailer shop that they can restore my scratch and a little cloudy headlamps to perfection. RM 400 and they will put the lamps in an oven to soften the rubber seals, open it all up, polish it inside out, and put it all back together again, with warranty against leaking. But the shop is the middle man. Anyone knows who is the real source? The person who actually does the work?Thanks!
