I did plastidip, but my car has the moustache and is white, so it improve significantly its look.
Now on your black car, I'm afraid it'll make the front end "boring". CF will look stupid, Matte will make a weird contrast with glossy black, and glossy will just make it blend so much as to look sorry. Maybe you could try to set it in bright glossy color, to match other colored items in/out (but that's bold). Would leave it alone.
