Our Golf 7 is just four years old but the headlamp lenses are already losing their shine and becoming slightly opaque. I spoke to the dealer about this last time the car was serviced and he said that it was basically the sunshine denaturing the plastic. "Try to park out of the sun", was his suggestion! As my handle would suggest I live in Italy so rather easier said than done. Anybody have any tips on restoring their gloss and transparency? I wondered about buffing them with T Cut but I'd like to hear from someone who has restored these before I take the plunge. Ciao.
