After removing my original windows I can assure you that Plexus is evil stuff and I would never use it again. I used 3M VHB tape and love it so far. It has only been one season, but so far so good. It is easy to apply and hold tenaciously. It's flexible (a very good thing), easy to apply and easy to remove (can be sliced with a sharp blade). So far, no downsides.
