I'd like to match the factory tint on my new MC's rear/side windows to put on the fronts and rear window. First, is it a film tint or is it a "smoked glass" tint on the new trucks? Does anyone know what color,type,or what % it is? Or, do I just go to a shop and pick the closest match? I'd like to get the same if possible so I don't have two different shades of tint.
