My 3M tint person told me there would be tiny clear/foamy air bubbles and a few hazy spots until the tint is fully dried out. He said the drying process could take as longs as 2-3 weeks depending on the weather (hot weather and direct sunlight is the best for drying faster). Unless you only have a 7 day warranty on the tint, I would wait about a month after the install date before taking it back. They are just going to tell you the tint is not dry and give it more time. After a month, then take it back to have them fix it, if the same bubbles/haze are still there.
Not all tint is created equally, not all installers apply equally
