Here was my post in it:
"I used it to drive my car across the country home. I also have the matte black stripes. It's really thick, and because of that it won't take curves well. The guy with that lotus must have spent a bunch of time getting it to look even that decent. So just expect a lot of folding and bubbles, but since it's temporary that doesn't really matter. I left it on my car for a week, and it left residue on the matte stripes that at first I couldn't get off, even with tar-remover. I thought that section of stripes might be ruined. What actually got it off though was just letting some soapy water soak into the residue, letting the residue dry, and rolling it off with my fingers."
To elaborate more on your question about how long it can be left on. The pieces I pulled off after a week came off easily and any residue came off easily. I left a couple pieces down on the bottom front of the bumper and didn't pull those off until 2 weeks later. At 2 weeks they were still removed relatively easily except from the area where they were on the matte stripes. So if you have matte stripes, just remove it within a week. If not, then even 2 weeks seemed to be fine. For coverage, at bare minimum you want to do the front face of the car, and the areas in front of and behind the wheel wells. Even though it seems counter-intuitive the area in front of the rear wheels is perhaps the most frequently chipped and beaten part of the sides of the car.
