I've had one on my '92 Teal for about 9 months. I am VERY careful to remove and clean VERY well when I do car washes. NO discoloration or "milking" of the paint!
I am painting the car right now, probably won't reuse the full bra w/fresh paint. Really used it for the same reason you are thinking about it(hide front body/paint damage).
I too like the looks, but am going to do a clear bra instead when I get the car back.
If you're interested, I'll sell you mine.
