...Australian sun...none more intense...AND the plywood will have bowed considerably due to sun further drying and shrinking the top veneer. I routinely 'change' the shape of unruly ply and timber with an 'application' of sun...and spraying the back side with mist of water can speed the process. The secret is to stop it just in time and then rest overnight inside. It can salvage unusable bits of any timber product, ply, solid or manufactured board..Good fun...now if we could just stop the fires...I'm 40km from the advancing front of the Currowan fire, now a month old and having consumed 265,000 hectares...and it's gunna be 39 C here on the coast and 46C at the fireground...keep a thought for us down here...cheers

Exactly. Internal moisture differential. Wood never stops moving. We just try to work with it when it's reasonably tame.
