Uh, the first night until the film cured, there was minor dispersion, but the next day and for the past year plus, it's been fine (35 sides and rear and 75 windshield).
The only annoyances have been two:
First, that the windshield has developed micropitting over time, and if I get it replaced, then I will have to pay another $400 to get the new windshield filmed. I would say tinted, but the 75 is all but invisible. The benefits are from heat reduction and very noticeable glare reductions.
Second, there are a couple of small nicks in the tint, thankfully not in the line of sight, that mysteriously appeared after one service visit or another. Now, I photograph the car from end to end, inside and out, before each service visit, and inspect it carefully before leaving. Not just for tint damage, but for any and all damage.
