Its very hard to show the true condition of the paint under my garage lights, the paint did deteriorate during the few years I didn't have a garage and it was parked outside all day at work.
When I moved to my current house and finally got a garage I had the car clay bared then cut and polished, so the car looks as good as it does in the pictures, however up close you can still see some hard water marks and spots.
This is a picture of the roof, which has never been resprayed, it's no where near as noticeable on the boot and bonnet.
