Yes, it was professionally painted and installed. When it comes to the job like this one I prefer dealing with professionals. I am a professional too, so it was a trade. There are only 2 upper bolts used but the whole part is taped to the tailgate and feels pretty solid. Oh, the spoiler had to be painted twice because of the fiberglass quality. The result is fantastic, you cannot tell this is an aftermarket installation.
I will try to post some closeups when I make them.
