I have a Deep/minion, Sunova and Naish LE boards - how protective do I have to be? How long can I leave it in direct sunlight (>30C sunny day) before it is damaged? I know you can't leave it inside a hot car - but what about on a beach? Are they OK in a board bag?

Last year I rigged up a little sun tent on the beach - they were treated like royalty... Seemed a little over the top...
