How did you reseal the windows? Did you use butyl rubber tape or caulk to seal the window frames back in the openings? Silicon caulk almost always fails and it's almost impossible to get anything else to stick when the silicon fails.
I do have the marker lights over the windows. I've unmounted each of them and resealed. I feel pretty confident they are not the source of my leak.
Replaced the existing butyl with new (same color/tackiness) butyl. Used silicon caulk under the black molding between the glass and the molding.
I had to replace a good size piece of the bunk flooring due to rot where water settled and couldn't get out. Chased the rot a bit but the side panels and roof are intact. I'm glad my bunk is one piece fiberglass.
The windows just weep, specifically between the glass and the metal frame during a rain, enough to dampen a towel over a couple of hours placed just below the windows.
This 3M stuff seems like it might just prevent any water from getting to the windows. As long as my assumption is correct (the windows are the source of the leaks) covering them completely in a shield of think flexible plastic should help.
Just looking for suggestions on alternative ways to prevent leaking since it seems most bunk-overs leak in these older models. Hadn't seen anyone post about using this material in this way. May just give it a try since the plastic is 100% removable due to it's intended use on car paint finishes.
