Question of window tint

You've probably considered this, but it bears repeating. Make sure the opacity rating of the film does not exceed state limits. I hate making the police nervous because they can't see into the car.

I haven't seen much in the way of automotive bronze. Try http://www.snaptint.com and look for SunTek solar films. These are mainly targeted at the home improvement bunch, but will work fine in a car if properly applied.
