I have the gloss black and agree with the others, at first you won't be happy about seeing the line but 12 months from now you'll be happy you had it. You really have to point it out to people that its there otherwise they won't notice.
Also do your headlights and all the other lights on the front as well as the bumper. It will save you anguish and time spent at the body shop or doing it yourself. I also second stradale's comments re the door sill, I'm going in to get mine done next week, it is a high traffic area that is easily scuffed especially by guests that aren't as aware.
