I got 20%. I was content on legal 35%, but looking around at all the cars with tiny, I saw a lot of 20%, enough that I wouldn’t stick out. I don’t drive like an asshole, and if I’m every pulled over I’ll just roll them all down a little to let in more light.

The two places on the Berlin Turnpike in Berlin are highly recommended. Pricey, but flawless. Seeing as how your looking for ceramic coating, appearance is probably high on the list. I didn’t get ceramic tints, I think they were almost double the price, but they are very high quality.
