I don't know if this example will help but if you haven't seen it you could look at NL Studio's WAS 8. I had thought it was rubber but when I looked it up it turns out it's clad in polyurethane resin. So seamless that they had to go back and cut out the doors once they put it on. Not bouncy though.

While I was trying to remember the name of that building I came across a building that DID use rubber on the facade, as soundproofing. It looks like they had to use rivets or something to keep it attached.
