Like 89LXNB I painted mine, actually I paid a professional to paint mine, they had to be sanded, filled, sanded, primed, sanded, and then painted. They turned out great, I think it cost me about $175. Well worth the money and less expensive then new quarter windows.
Try to find someone who will do a good job for you. I ran into the guy who did mine at a car show, turns out he owns and operates a body shop and is a Mustang enthusiest. That's the kind of guy who will pay attention to detail and do a great job for you.
Or if you're handy at that kind of thing you can do it yourself at home, a friend of mine did his and they turned out pretty good too. Probably somebody here has done it and can tell you the materials you will need.
