I had used Com-Paint in multiple locations on my exotica red Punto. As you have discovered color match is fairly good. But because they use bad quality spray nozzle, spray does not come out as even fine spray whatever circus you do. It ends up in a grainy finish. I have tried everything I read on the net to try and fix the problem. But I could not get a good finish after spending considerable time experimenting with it. One workaround that helped to some extent was spraying the clear coat on top of compaint which comes out fairly smooth. I believe clear coat viscosity is very different causing a fairly fine spray. It did not look that ugly when I finished the job. However, my happiness did not last too long. After a year or so I am seeing com-painted areas are slowly changing color. They are getting a slightly darker shade, as if com-paint has got sun tanned! I feel com-paint may work for white color or light shades. Definitely it will not work for exotica red kind of shades. I have not taken this problem too seriously because Fiat features like ride quality are keeping me very happy, helping me to ignore the externals for now. Also, I cannot afford a 10-15 thousand Rs. professional paint job when the EMI is running and the oil price continues to burn a hole in my pocket (my Punto is a PetPunto - Petrol I mean). I am planning to get a pfofessional paint job done next year after my EMI burden ends.
