Wow New York Tint laws
are strict, 70% on the side windows and anything on the rear window.
70% is lighter than almost all the window films on the market.
The only thing that probably qualifies is this new type of window film that is extremely light (70%) but still blocks 60% of heat from Huper Optik or V-Kool window film maufacturers here at this Car Tint Site
, but both of these types of films are super premium, very expensive.
Good Luck... You will probably need to get the window film removed now too.
