So I had a plan to paint the mirror covers.
Seemed simple enough

Wrong, after speaking to a few people including Thom, it was still not clear on how they come off, so today rung Skoda who confirmed that the mirror glass needs to be removed and then you will see 2 screws behind which hold the cover on.
So tonight armed with this new info I tried again and broke the mirror glass

so have now given up painting them as a bad / stupid idea and in the morning need to order a new mirror glass.
Why is it what looks to be a simple job ends up a complete ballache.
