As you mostly know, I have a new 05 reg Astra with nice shiny paint.
A week ago the O/S wing mirror and the panels on the N/S got splatted with some weird white stuff - Much worse than bird muck as it only came off by scratching it with a thumbnail.
So I very gingerly rubbed it with a plastic scourer.
All looked fine until I check it the next day.
BIG scratch marks all down the side and all over the wing mirror!
Thought I had totally wrecked the paint and was shocked at the damage (I'm very careful usually and thought the plastic was easily soft enough)!
Luckily some paint coloured Turtle Wax polish did the trick and it's now only visible if you look VERY hard.
Thank f**k for that!!
