Best nose protection from debris on long trips?

When I took possession of my C7 in Bowling Green, I had pre-ordered a nose bra to protect against rocks and other road debris on the drive to Nevada. A rep at the museum tried to install it, but became concerned that it might "flap around" and damage the paint when it didn't fit tightly. I had the nose bra returned to stock from where it was purchased!

I'm wondering if anyone has had good experiences with a specific nose bra and can recommend it? I decided not to go the 3-M film route, but perhaps there may be a temporary film that can be put on and easily removed for lengthy road trips?
Many thanks
