You know, you can go to a jobber shop, a NAPA that has a Martin Senior paint counter or what have you and have them stuff a rattle can with a good quality auto paint of your color. Just let them know that it will be for plastic. There is more to it, mainly in the prep, but you can do it your self for not much more then 50 bucks. If you want to think about it, just follow the steps in the thread about painting your cladding, think it was Mark Miller that wrote it.
