Balsaloc (I think this is water soluable)
HIPEC fabric cement (used for full size fabric covered airplanes and dacron covering, works well with silk haven't tried it with anything else)
Stits Poly-tac cement (also used for full size fabric covered airplanes)
thinned white glue (works very well attaching balsa to foam cores! Just put a coat of thinned white glue on the foam and on the balsa, let dry, iron the balsa into place)
Has anyone else tried alternatives to Balsaright? How well did they work?
