Try Detail Master -9202 in factory blue-green and also a sort of dark gray. This is a decal - I have some but have not yet tried it. It is meant to be used for window tinting.
I read an article in Scale Auto magazine, a model build - the modeler used Testor's window spray tint on the inside of the windows, then oversprayed that with chrome alcad (or maybe I have the order reversed). Anyway, it was an incredible look. Not simply a 'chromed' window. Since the black is partly 'see-through', so is the chrome partly see-through.
I have read that some modelers have tinted Future floor polish with food coloring, the dipped or sprayed the window - have not tried it myself. I would also only put this on the inside of the window, as Future is somewhat soft and might be damaged if on the outside of the window. I think it would be possible to just flood the surface, or use a soft very wide brush, then drain well. Might require several 'dips', depending upon how dark you want the tint.
