As far as protection goes, our 2002 Z28 we've had since new still shines well with periodic Zaino treatments since day 2 of ownership from the dealer. And it lived 99% of its life out in the driveway and hot sun of the south. So I'm a firm believer of Zaino helping preserve a "yard" car paint job. It's all the car has ever had, and the paint still shines extremely well. And it's metallic pewter.

Oh, and you had a question about the windscreen too. I'm assuming you want to leave the screen installed but lay down the top of the screen. Just grab the bar and give it a firm push back and the top should lay down. (it has a detent system so you should hear an audible click)
