What causes film to roll off glass?

Answer 1: This situation is becoming more and more common in the modern era with new window technology and tinting products. Basically, manufacturers are using less glue for films with higher VLT rates.    Answer 2: There may be too much silicone in the dot matrix. This can cause the film’s adhesive to fail.    Answer 3: This is especially common in warmer weather, so you may need to press the film down very quickly if you see the film start to roll off the glass.    Answer 4: If you’re using oil-based cleaning sprays, this can affect the film’s adhesive performance. Honda dealerships are especially well-known for using oil-based sprays. If you think this might be the case, use a mild solvent to clean the glass before installation. Another option is to go over the window with a solution of alcohol and water before installation.
