Glad you don’t have to worry about it.

BJ - I've wondered the same. It's been my observation that these things warped (if they were going to...) pretty quickly. I saw it commonly even back in the '70s.

My guess would be it had something to do with disparate temperatures of inner / outer panels when they were bonded together, or a different rate of shrinkage between the resin in the inner and outer panels after they were joined. It wouldn't take much....

Just a guess, though - my experience engineering hood systems is all around the metal variety.
