I found that when I used lubed cushion wads the lube on the inside of the brass prevents any glue from sticking. Now after inserting the wad and before adding shot, I wipe the inside of the mouth thoroughly with an acetone-dampened rag, and then I use waterglass (sodium silicate) to secure the overshot card. Seems to work.
