ok, i know there are many different companies making these now, Cervinis just added a new one to their line as well. it actually covers the factory holes with little fiberglass/urethane pieces that go over the holes, but you have to drill new holes in the trunk lid to install it. i have read the Street Scene Ducktail, and the 3D Carbon (3 pc) just double side tape down. wondering if anyone on here has one of those that just tape down? wondering if just the tape will hold these without the risk of them flying off? i use double faced tape at work, and it holds pretty well. it will stick a 250 pound hutch to a desk, that will take 4 people to get loose, but wondering if it holds as good on a spoiler? i am going to be changing my wife's spoiler very soon, hadn't yet due to she hasn't found one she really liked yet, now it's between the Cervini and Street Scene. i appreciate any info/help you can provide...thanks
