I agree with Steve F. If you are not taking the windows out and apart I would prep with wet sanding paper, clean with detergent based cleaner and follow with a chemical cleaner such as DX330(ppg product). Etch primers work very well when properly applied but proper application is not simple. If your film thickness is too thin the film fails. If your film thickness is too thick then the film delaminates from its self. If the grit used to rough the metal is too rough the etch primer can fail. Use a decent automotive grade spray epoxy primer(available in black) and finish with SEM trim paint. Make sure the paint is warm and well mixed and the window frames are warm as well. If the frames are out and apart I would visit the powder coater.
