It's all plastic under there, so it's not like the little holes will rust or anything. I used tape, but when it started to fail, I used short screws and it snugged shit up noice = ain't goin' anywhere. I attached mine right against the back lip (there's a verticle 1/2" lip an inch or so under the front edge of the bumper) so it doesn't stick out so far, and I like the look a lot better. Different strokes for different folks though. Bottom line, if you like it then do it. I'm sure there's plenty of stuff on my car that different people like or don't like, but ultimately what I'm happy with is all that matters. We've all seen cars that make us roll our eyes and yet, that owner likes it and so does at least one of his buddies or family members that's encouraging him.
