3m crystalline is a ceramic window tint that markets itself as rejecting a lot of infrared heat, but always performs less than advertised. They’ve been sued a few times because of the false claims. It’s better than no tint at all, but it’s overpriced and doesn’t perform as well as it’s competitors or what it claims it does. Plus it has bad low angle haze and some distortions and apparently for window tinters and installers, it’s horrible to apply. Bad adhesive and doesn’t shrink properly and has some other issues. Usually people get it because it’s the first Google search result they find. And 3m is known for its name brand and marketing, so people don’t second guess it. I’d rather run no tint at all than any crystalline. That’s how bad it is
