Thoughts on a 3M clear bra

[moymch]

I found a place here in Germany who applies the 3M clear bras. Does anyone have one of these on a black vehicle? I have seen them on light colored cars and they look fine, how does it show up on dark colored cars? The guy is going to give me a good deal for my X3. Total front mask, 12 inches on the hood (or less if I want), front fenders to match hood and mirrors for 300 Euros less tax. How long do these bras last and do they fade or yellow? Thanks for the help.
