the LS-7WL I flew for a few seasons suffered from "fishing lure" syndrome: someone left the canopy open on a windy day and by the time they realized the mistake it was wobbling in the breeze like a Dick Knight spoon. it did require some adjustments to the mounting hardware to realign with the latching pins. never was back to original condition, but it was/is manageable. keep those canopies CLOSED when you are away from the aircraft.
