Have you washed the window castings? Most plastic kits, including rolling stock, structures, etc. will be easier to paint, especially with water-based paints, if they're first washed. In addition to any mould release agent still on the plastic, oils from your skin, through handling, will be deposited on the surface, making paint adhesion less than ideal. Liquid dish detergent in warm water will remove this - rinse thoroughly when done, or you'll have a problem with the paint not adhering to the detergent film. Another option would be to dip small parts in isopropyl alcohol, although I'd keep the cleaning alcohol separate from the stuff for paint thinning or other uses.
