paint protection

[tonypotton]

I am ordering a new Boxster from Germany and wonder if anyone has any direct knowledge of using a paint protection system such asinvicta-shield or armourfend?The idea of not having stonechips seems a good one.Does it work? Canyou get just part of the car done eg front? Does it take polish like the ordinary paint and is it invisible?Has anyone had it done and do they recommend it?Any views on this will help.
