I bought a qty of 5 2ft x 5ft lengths to do graphics on a quarter midget race car. (Needed to be cut in a vinyl cutter] First off, if kinked this film discolors leaving a visible mark that cannot be removed. One of the pieces had a clear kink acrossed the film when onrolled from the box. Luckily I was able to make my cuts around this and didn't have to waste the entire piece. I think this should have been noticed before shipping it out to me. Second issue is with the air channels. Air channels seal up with very minimal pressure trapping air under the film. I have used film that had much better air egress. The film looks nice on the car but was much more difficult to work with than others I have used in the past.
