Very hard to install second layer of film onto the first one on the Ipad, impossible to squeeze out air bubbles from under a second layer of film, it sticks so fast and strong to the first film layer immediately. Also enclosed in the package black rubber squeezer crumbles off when installing the first layer of film, and these pieces of black rubber are not noticeable until the second film layer is applied, after which it's not possible to separate the two film layers to remove the tiny rubber pieces. These rubber pieces in between the film layers are very visible after the Ipad is turned on and the screen is white. I wish there would be a single double-thick film that Clear Coat is selling for Ipads. Seems like a good product, but installation on the large surfaces is not very user friendly. I would love to buy it if it's a single double-thick film product.
