I have not installed a saleen wing, but I have done alot of other stuff using 3m tape. My advice is to put the tape all the way around the edges. Then instead of pulling off all the backing, just get each segment started about 1-2 inches and fold it over so it sticks out from under the wing. Then you can still slide it around and get it where you want it without it sticking. then when you get it where you want it hold down tight and grab the little 1" piece of tape backing sticking out from under it and begin pulling. The backing will come off with the wing positioned perfectly. You really need 2 people for this 1 to hold the wing in position and 1 to pull the tape backing off, but it's the easiest way to get it right.
