those bra are nice for long trips in the dry, but don't let it sit on there if it gets wet. You can easily end up with a line across your hood and fenders from where the bra traps the water which has all kinds of dirt and dust and general crap in it and then it rubs your finish. This is what's happened to my wife's Malibu with one on it only during the summer!
I have one of the front edge of the hood ones that I put on when I take a long trip, but I take it off as soon as I can once I get where I'm headed.
