Lexel, maybe? Ace carries that, $11-12/tube. Only clear sealant I
know that really sticks and stays rubbery. Silicone isn't as clear.

No... I've used the acrylic/styrene solvent-based sealants, also. They
are tough and rubbery. They do NOT stay "wet" and gummy on the air-
exposed surface. They skin over quickly, self-level well, and are great
sealants.

But you'd NEVER get a window back out of a steel door if you glued the
whole flange to the door with that stuff.

This sealant was cured on the door, still "wet" on the window side, and
very, very soft, so it complied almost like regular caulk when the window
was screwed together.

May be they just brush on something that inhibits the cure of the sealant.
There are a lot of things that do this to silicone. Maybe it was not even
intentional?
