As a newb, I've just done this for the first time and I was very wary of the oven method, but still went ahead and did it, devil that I am, lol! If anything is about to go wrong, then it usually is with me it goes wrong lol! Put the stripped doen headlight in the oven for 15 mins at 100C and it came apart easily. When the lens first separates from the body dont pull it apart too far, as Andy B stated, run round the edge of the lens with a stanley blade to break apart the goop so it doesnt droop onto the headlight inner reflector parts. Just waiting for ally adjusters to arrive to put it all back together, very easy job to do, well taking it apart was, maybe thats an omen lol and the blank up will appear in the rebuild process lol! Wish me luck, dears! As a side note, I think what probably puts most is probably the thought of heating the unit, after 15 mins in the oven, the unit could be handled with bare hands and was still firm to the touch (fnurr) and no deformation, well, apart from me lol!
