I've read the a4 mod site on how to strip the headlights and it says its not as easy as putting them in oven to separate them. Now I only want to blacken the long chrome bit at the inside front of the headlight, not bothered about blackening the rest. My question is, why can't I just put them in the oven to separate the lens? I done this with my Fabia vrs headlights with no problem at all. 70c for 10mins done the job perfectly. Can I just pop them in the oven????
