What should I know / consider about window tinting? Going to have this done to my car soon.

My state law says tint "must allow greater than 20% light". I get the feeling I can't just request 21% VLT tint. Am I wrong?

>my law says i cant have more than 20%
>do you think i can have 21%

I figure it comes in discrete increments, right? 25% maybe?

You mean you can't get less than 20%

See that's where the verbiage is tricky. From the resources I've found online, it reads "Must allow more than 20% of light in.". I'm looking for the actual legal text right now.

Right. 5% let's 5% of light in, that's why 20% isn't as dark as 5%.

Do whatever you want, undercover cops have 3% tint and so do I. I got pulled over once for my tint and I told the cop I can't even see in your front windshield and you're telling me my tint is illegal? Got off with a warning.

OK, found the actual legal text. It says "shall have a light transmission of not less than twenty percent".

So those online resources that claim to have details of the law are reading it wrong. Looks like I can indeed get tint rated at 20% VLT.

Are there benefits / downsides to getting a more transparent tint?

So then what's the beneft other than style? Seems like 20% should keep fairly private and keep heat down.

>benefits
lets in more light so you can see
>downsides
lets in more light making it hotter

Go with any tint you want, it's not like cops carry spectrometers on them. 20%, is pretty light go with ℅15
