longevity of clear bra?

[Blue Mountain Raider]

hi i've been reading here that a lot of people have gotten clear bras along with their rides and i think its a good idea. just wondering though, how long until the bra starts to peel if? if ever.

i ask because some of the pics members posted you can see the lines on the hood, so after many car washes and the weather won't water begin to sort of make the edges of the bra start to come off? thanks.

by the way can you apply the same protective film on your wind shield to protect it from rock chips as well?
