Drying time:

Your new window film will take about 3 to 5 days to fully dry, sometimes a lot longer depending on film brand, type, and weather conditions. Until this time your tinted windows may appear hazy or lumpy, and it may seem to have water bubbles. Do not roll your tinted windows down until dry!

Cleaning
Window film may be cleaned with a soft clean cloth and alcohol based cleaner or plain water. Ammonia products should not be used. 

Black dotted edges
Most cars have a black ceramic 'frit' edge on the rear window.
