Martin Logan CLS II spacer adhesive become loose

Dear Forum!

I am asking if it is possible to re-glue a portion of a Martin Logan CLS II panel that has started to split at the top of the panel (see attachment)
My plan is to find the suitable glue to reattach the split stators. I have some nice clamps to do the job, and glues (eg. chinese 'B 7000' telephone glue)

My question if anyone has any idea which type of glue would stick to the polyurethane(?) spacer and the diaphragm foil?

If it were mine, I would try and clean with a rag pulled tight over the end of a putty knife and some acetone
to get into the tight corners.
Either jell super glue or gorilla glue polyurethane will work fine with clamps
The good thing it’s near a corner so less impact on performance and this goes into the wood slot as an additional fixed
working position anyway
