I agree that the acrylic is stronger and more likely to be the source of the
stresses. The benefit of undercutting the fiberglass is that it makes it
easier to counter the acrylic forces by removing the support to the
fiberglass, but it would take some fixing element, such as a plate, to keep
it from curling up even more. BTW, how do you recurve the rear hatch?

That might be an interesting experiment, lets start with your... just
kidding
;-) Maybe something to try with a discarded piece of junk acrylic but not
if
it is at all usable.
The acrylic is bonded to the fibreglass, but is the stronger of the two
materials and when the acrylic curls up it pulls the fibreglass along. If
you cut from the bottom you will be cutting the fibreglass which is
resisting
the acrylic. It seems to me that would make things worse if it did not just
break outright. The acrylic is very strong and has a tendency to flatten
itself out. That is why the rear hatches flatten in spite of the metal bar
inside and have to be periodically recurved. Maybe someone can comment on
his experience with the plates under the headlight covers
