Must admit that I've only done the f/o/s up to now, weather is against me so it'll be one of the first jobs when Spring arrives.
Whilst I'm in the mood for admitting things here's why I had to buy new ones, *hangs head in shame*. My headlights were slightly cloudy & the Internet said you can just replace the outer plastic lens, much better than trying to polish them.
Bought a pair of new lens covers from France & as I broke one of the headlight retaining clips prior I also bought two sets of headlight repair retaining clips. The Internet also told me to put the whole headlight unit in the oven at 210° for 14 minutes to melt the adhesive seal. This I did with the precision normally associated with a bloke, other genders are available etc. Went for a quick wee & on my way back into the kitchen I thought........"Mmmmm, that smells like burning plastic?".
Yup you're correct, as soon as I left the kitchen the headlight must have moved off the block of wood due to expansion (or contraction) & both the front & rear of the headlight resembled that painting called 'The Scream' by Edvard Munch! Anyone want to buy some modern German artwork?
Bloody Internet,pmsl.
