I stumbled onto this thread yesterday & ended up reading the entire thing, stumbling off to bed well after my bedtime.
Wonderful stuff.
One (of many) things that stuck in my mind was a reference to cleaning FUD making it frostier. This morning I started wondering what would happen if after cleaning, you coated (areas) with clear gloss, possibly with some mechanical polishing first. Would that create sufficient transparency to pass for glazing?
You could then mask windows (or entire window areas) and paint, remove mask, apply laser cut windows surrounds (or multiple window strips), and possibly have near-flush glazed windows with less overall effort, or better results, or both.
Might be worth some experimentation.
