Side panel security

Hi guys, whilst out Sunday for a ride in the sunshine had a side panel come off for whatever reason.
Fortunately no one was hurt and no second party damage just a need for a respray to the offside panel.
Whilst this has never happened before I was wondering is their a method to firmly secure the side panels that does not destroy the look/lines of the panel. I have both Li and GP scooters that I would like to protect against such an event happening again.
All advice / ideas greatly received . Jono
