If your airplane gets above 150 F you will have other problems. 150 F cooks flesh. We post cure in aerospace because the designers cut the margins thin knowing we had proper process control.

No mold less construction airplane that I know of has had heat distortion problems post cure or not.

Much ado about a statistically non issue.

Time promotes cross linking and that is all post cures do is further cross linking.

I see your point, but as far as I know this does not apply to the glass-transition temperature.
