They're frameless... not port lights... the cabin windows.

I believe the guy mentioned something about a 2-part
mix that he uses.

That sounds like trouble to me. It does sound like he is talking
about Plexus. If (when) you need to remove/replace/rebed you are going
to tear up your cabin top getting those glued in windows out of there.
Just my opinion. Do your portlights fit into a recessed opening or do
they attach to the outside of the cabin top? The real problem with
large, frameless portlights is that things move and expand in
different amounts and different directions. Each one of my portlights
(two per side for the main cabin) are probably 3' long, from memory.
They are recessed and sit in silicole bedding on both sides. No
mechanical or structural stresses to cause leaks.
