I bought a car (used) and the seller told me it had Huper Optic Ceramic. I've seen that tint in the shops and its amazing how it blocks the heat and it's overall quality. Although I don't think he was lying, or mistaken, but how can I test that? I'm sure I can take the meters they have in the shops and test it to see if it matches specs but I don't have that meter of course being an end user. Ditto on not having those heat lamps they use in the displays in the shops.
Any ideas? If there is an installer in my area (Los Angeles) that can test it, I don't mind paying you a "consultation fee" for peace of mind.
