The quality was great, and the cut was dead on, but I had difficulties getting it to lay flat, even with heat. The heat just made the slip on the opposite side evaporate, leaving soapy residue which increased friction. This caused the film to crease in a few areas, and was no way to get rid of the creases/folds. I started with the back window, and had to discard the piece due to the creases, leaving me with the full kit…. minus the back glass… No idea if I can even order just the back glass, so I guess my tinting days are over. Not their fault, it’s just very difficult.
