I found I could gently pry the frame out of the opening with just a thin
putty knife, but when I got it out, I found something that surprised me.
The sealant the manufacturer used had the properties of both a silicone
sealant, and a non-hardening, clear "goo" -- the gooey part acted like a
conventional putty, but the hardening part acted just like regular
The bead appeared to have been gunned onto the door, then allowed to cure

silicone would be (although it was a bit softer and more elastic that GE
Silicone), but the gummy part only adhered to the window frame by its
tackiness. It was a perfect sealant, in that it compressed fairly
