One of my neighbors has a strip of clear bra on a white car that has turned the color of dark urine. I should take a picture of it when I get a chance. I suspect it's one of the $25 eBay ones because none of the genuine stuff by any manufacturer should yellow that badly. The eBay ones are described as vinyl so I don't think they're even the same material as the genuine stuff which is urethane.

You can get the genuine stuff for $6.68/linear foot at 18" width. That won't cost much more than the eBay one. Line it up on the front of the hood and apply it from rear to front. Once that's done, just trim to a 1 cm border around the edges of the hood and wrap them around. It's much less likely to peel that way and you don't really have to worry about aligning it as you would with a precut piece.

I did the entire hood and it turned out pretty well. The tint shop thought I did a good job as well. I'm going to do the mirrors tomorrow and with the whole front end of the car covered, I can engage in some mad drafting on my trip.
