Re: Spider door mirrors - flaky paint
I did mine not too long ago, probably in August/September and it made a huge difference.
Mine were pretty bad, so decided to take them off, sand them down (wet n dry) and then prime/respray in black gloss (spray paint can). Took a few coats, spraying lightly to get an even coat (so that it doesn't drip/run).
They're quite easy to take off, the workshop manual (pdf) that has been kicking about on here shows you exactly how to remove them. They come off in three bits, 2 metal and obviously the plastic mirror bit.
I Seem to remember loosening the door card a bit to get the allen key in for the final screw (little bit fiddley)
Used the remainder of my black gloss to touch up the wiper arms, as they were a bit tatty.
You'll have to post some pics, when you've got it done.
