The roofbar project-ette!
As mentioned before the official roofbars from Fiat are shocking - the powder coating has peeled off because the under-layer has reverted to powder and, as I am sure you are aware, powder has little or no adhesive properties!
I have undertaken to respray mine to match my car and it looks ok! Pictures attached.
It is also worth noting that for a large roofbox to be fitted in the optimal location the aerial needs to be bent, so I'm about to instal a shark-fin - also blue.
