Getting the film off if is a bitch, worse if it's left on there longer. I had to have mine taken off after about a week and it left a sticky residue on the hood. My installer had to rub off the residue with Goof off and if they do this, there is a high chance of leaving scratches because considerable pressure has to be applied to get the crap off. My hood has a *hit load of scratches because of this.
