Hi There, this maybe a long shot but what about some tamiya polishing compund rubbed on with a cutex or ear-bud whatever you want to call it?? You will probably lose some paint on the framing, but that can be touched up later. I have tried this and it worked for me, I actually had super glue on the canopy. So basically, rub them down, which should restore them to their original transperent selves, then re-future them, and touch up with a final coat of future to seal the whole lot.
Hope this helps
