Heh - ok well my question is about whether to make it literally permanent, and you're suggesting a temporary (even if it's years) seal. I'll use epoxy caulk on it then ;)
My guiding principle at times is, "If someone else has this bus in 10 years, will they curse me for doing this?" If I actually epoxied the entire window in, I'd have a fantastic seal but never, ever get that thing out. But if I epoxy that gap and use std. caulk for the window, I don't think it's going to cause any grief.
