Well, no need to say that’s another great model.
Humm, always used X-18 (actually 85 from Humbrol) to paint the window frames and with good results.
Two suggestions, use especial masking tape (I use Tamiya Masking Tape) to help you and wait at least one week after the last coat before painting the frames.
If the body paint is not totally dry it can react with the frames paint.
