Spaceships and aircraft yes. Trailer at highway speeds, no?? :-)

There's a whole world of adhesives out there that don't come from Home Depot...

Above is tongue-in-cheek. As others have said, 3M VHB is widely available and has peel strengths way in excess of any mechanical or aerodynamic load you could put on the panels.

Should the paint be stripped off of the surface before using the adhesive? I've seen very impressive adhesive mounts fail - not due to issues with the adhesive but with the paint that the adhesive was sitting upon debonding from the base metal. I assume that would be in play in this scenario as well, no?
