Break out the drill and drill the corresponding holes in your trunk for added security. I'm a neat freak so I would tape the where the holes are going to be, on both sides, top and bottom then center punch where you're going to drill then slowly drill into the trunk. The tapping and tape should keep it from scratching anything. When you remove the tape. if any of the paint is lifted then use some touch-up paint on it. Let it dry then install.

yes, clean it very well, then tape it on. did it not come with screws? if not, putting a few into the sides where it wraps around to the fender well won't hurt.
I was thinking the exact same thing. Maybe that's because I just got my front lip painted and was contemplating how to put it on.
I did however install my own trunk spoiler also. It came with all the stuff (minus drill and bits) to drill my own holes and mount the spoiler. Wasn't too hard. When you drill though, I would recommend to put masking tape down first so your bit doesn't walk.
