I personally do not use Clear Bra's as they will effect your paint, regardless. Esp with those leather bra's with sun exposure, and fading paint, you will notice the difference between the two shades.
but with the clear bra since it is see through, the paint shades wont be too diffrent.
Also it can be sold as an universal product that you can get professionally installed by an Audio Sound Guy or people who know how to do Wraps.
If you still think the Clear bra doesn't work, and rock chips eats away @ it heres my buddys beamer that was hit by a car , that most defiantly if it was a leather bra it would of damaged the car.
As it show in the pictures the Paint was saved, you can judge your self which one is better.
