But the silicone is designed to be adhesive.

Good point. Our aquaria have the silicone holding well on glass.
Indeed, we have had to shave it off to clear the glass!

We have not had as good a result with plastics. They have to be
really clean and the bond really good. I wouldn't want to run with it
without compression to hold things steady.

Maybe someone can get with a manufacturer to talk about bonding and
flex.
