I picked up a bottle of Dave Browns Southern Sorghum contact glue for sheeting foam wings and used it to sheet a small part of the hatch on a plane I'm building. I used it just as the bottle said and it seemed to work well but after a few days of the part sitting on the plane, the balsa sheeting is letting loose from the foam core and the glue seems very sticky. When I push the balsa back down it again sticks well for a while but then lets loose again.
Am I doing something wrong to make the glue not hold the sheeting?

Thanks for any help

I used to be a beleiver in using sorgum until I lost a 42% formula one racer, use epoxy, that sorgum is a looser! If you leave your airplane in the sun that stuff will debond!

So if I can get the sheeting pulled off the foam without damaging the foam, can I put epoxy over the sorghum?

No, make a new hatch and use epoxy.
