Hope it's ok to post this question here I wanted to know what the best brand for tinting your car windows not going to do it myself but when I go out looking for a tint shop I wNt to be sure they are using quality stuff thanks so much in advance

Viper is pretty high quality so is SunTek.

I will never tint windows with anything less than 3M film.

I have SunTek on my windows.  Pretty good looking stuff and it's the only film the guy I had do mine has used in his 20-some years.  He is also the guy the state uses to tint their government vehicles in the area.

So he works on the cheap.

It was pretty cheap, but gave me a lifetime warranty against fading, cracking, and bubbling, so I'll just have it replaced if it gets to that point.  Saved me ~$30 on just the front two windows.

I have LLumar film on my car and it's what we use at the shop.

No issues thus far.

LLumar and 3m and Huper Optik are the best
