Hi,
I had a look at it tonight, whilst there is some surface crap it doesn't seem to align to the marks at all. I had a go on it with some autoglym colour restorer and it did nothing so am resigned to ignoring it (respray isn't really on the cards as unless it's just washed clean it doesn't look that noticeable most of the time.
Chris, it gets washed with some fairly general wash/max stuff from Halfords, always dried with one of those drying towels and infrequently polished with autoglym super resin polish. There's no chance I'm making this problem is there?
Lastly there are a number of power stations near us and it's more noticeable here than anywhere I've lived than the car can get dirty after a few days just sitting outside and not being driven
