any type of two part "multi-panel" adhesive should work should u decide to fix it... clean off old glue with mini sander or very carefully with grind disc. be carefull not to eat into the fiberglass door frame. once that clue is off scuff surface with some 100 or 80 grit sand paper and do the same to the door skin also... run a bead on the door frame all around and then on the skin all around. spread it out smooth with a plastic spreader so that the bead is now flat. on ly like 1mm or 2mm thick. and plop skin on making sure its straight and lined up like it was before and clamp it down with some spring clamps (be sure to put rags on the outside of the painted body so you dont scratch paint) come back in 24hr and remove clamps... should be good as new.. or look for used door is easiest but will cost alot more then a $40 tube of glue and some sand paper
