I only use the bra on long trips. I've got a full nose bra for that but it comes off when I get to where I'm going. I hate bugs and rock chips on my bumper. Anyway, I had gotten something up under the hood part and the weather hadn't been cooporating so I could polish it off. Its better now. I've only had the bra on twice this year. They are pretty high maintanance so if you get a bra be prepared to work.
