They should be fine then if you dont abuse the back window. I had white ones on y SE and my friends used to always role down the window when they were back there and about 6 months later letters began to disapear.
As far as under the hood goes. I actually was planning on giving it a try. Only problem is that the SVT wont be on the road until spring, so i am not 100% sure how it will stand up. And i depends on where you want to put it under there.
Send me a PM with exactly what you want
