Cold weather and humid conditions can lengthen the dry-out time, while warm, sunny weather will speed it up. Dry-out times can vary from a few days to as long as six months, but the film will eventually dry completely. Moisture that is trapped during the installation process can cause bubbles or a slightly cloudy appearance. This is normal. Do not try to pierce or cut the film in an attempt to drain the trapped moisture. This will damage the film. Just be patient and allow the film to dry completely on its own.
