While we may disagree on how to maintain a clear bra, one thing all of us agree upon is that it really does save your car in the long run. My clear bra saved me around $1500 in repair bills when a bolt hit my hood. The bra took the brunt, and the scratch was easily polished out. Without a clear bra, it would have been ugly - definitely a full repaint of the hood. Replacing the hood took a couple days with no downtime, just imagine how long a body shop would need your car for over and above the cost in order to fix a bad scratch.
As for its appearance, mine is over a year old, my car is AW, and there is no yellowing. You can see the faintest colour difference when you're right up close, but otherwise, it looks great. As long as you maintain your clear bra somehow, it should hold up pretty well.
