I agree with Viper.
You have to put it into perspective. If I had a 2005 steel car I would probably be dealing with rust and other issues.
The areas where dirt collects cause the issues.
Top corners of the windscreen.
Around the front indicators.
In the wheel arches.
Around the rear light tunnels.
These seem to be consistent on the early versions of the Aero.
Consistent cleaning so no deposits build up along with the use of ACF50 seems to be sensible. When you think about it you treat the painted surfaces with expensive waxes.
