If tint is common (and legal) where you live I'd just have a tint shop do it. Why? Warranty. I have all my vehicles tinted. They are fast and use superior, commercial grade products and they are reasonable too. Also, any problem I've ever had they don't ask questions, they just re-tint it for me and get me out of there.
If your windows are not installed then it's even easier, just drop them off with them for a day or two.
Currently vanless. Weird.
