the debonder i use (i dunno, says hobbytown brand) smells strongly like acetone and the package says it contains nitromethane. great stuff, especially for getting sebast silvestri stickers off my funtana....oh yeah, and ungluing my finger from the covering after i CA'ed the hinges. Its good to get some debonder anyways, its also great for cleaning up CA that dribbled down the fuse or whatever.
For the prob you have, go with FHHuber suggestion on filling and shaping..more strength=good
