How to protect underneath the frame? I've searched and only found this and this. But what I am really after is on a solution on how to cover/protect the underside of your frame.

I have a carbon road bike with mostly a white painted scheme throughout the bottom side and it's starting to show small chips already. Is there some form of transparent coating (think PU or some other stick on plastic) that I could use, later remove once too damaged and replace again to give my frame more life?

Any suggestion appreciated. Thanks
Get some Factory Effex Frame Protection Material, It's a vinyl that you just stick to you frame. You can get it in Black, Clear, or Carbon.
