Just a thought here, do the abarth owners get it as bad, or does the rear spoiler help move the low pressure area away from the boot so it doesn't get so dirty?
I have the Abarth spoiler on my TA and I don't think it makes a difference. If it does, the window might stay cleaner but the paintwork is unlikely to see a change.
You don't know dirt till you've lived in a semi rural village in the UK in the winter....
I see your dirty arse and raise you a shyte-splattered sillI find it's easier to simply ignore the whole dirt issue and concentrate on having fun:

The best way to keep the back clean would removal of the stock roof extension and adding a downdraft spoiler like used to be popular on station wagons.
