Well I'm surprised you could walk away without it falling off the glass. I'd say if you got enough fluid out to stay up, it would be fine. If it were me, I'd try to swing by some older install locations and just scope them out and see how they're doing.
The one time I've tried to wet apply something with air egress properties, it would have jumped off the panel if it wasn't laying down flat. Had to lift it off and hang it up to drip dry while cleaning off the panel. In the end the adhesion wasn't what it needed to be and I re ran the panel anyway.
