Heater box flap foam started to disintegrate. Any way to, re-enforce it?

Thanks, Huw.  Got it from HD.   I still have applied a hair think layer 
of silicon, filling the pitted spots.  Seems like it should hold it 
together.     Will see about the weatherstrip sometimes this week when I 
will assemble the box.   I might just applied baby powder to silicon to 
prevent it from being sticky.
