Thought I'd recommend EyeCandy detailing in Adelaide after my experience for any local Alfa people thinking of getting their cars ceramic coated or PPF wrapped. Just had the GTA detailed, ceramic coated and got the b-pillars vinyl wrapped as the stickers were missing when I bought it. I also had the side skirts PPF'd as these get hit hard with rock chips. They did excellent work at what I thought was a pretty reasonable price. I've put up some links to their work. They've done quite a few Giulia's going back through the history.
