hi everyone need an opinion...i want to tint the windows on the x but i dont know if i should go with a 20% or 35%...i have seen both and one appears to be to dark and the other to light..my x is sterling gray(dark gray) with light gray interior..usually with a light interior you can get away with the darker tint..thanks rob..also can anyone recommend a reputable installer on long island or the boroughs..thanks
