I don't think it came out of a tube. One small spot
seems to be almost intact and looks like a foam strip.
Definitely too defined an edge to be from a "squirt".
Can't tell if it is open cell or closed cell though. I am
wondering if it was put in but FR - for a valid reason -
or by the PO for some ????? reason. If if is there for
a good reason, maybe I need to replace it with a new
one. Otherwise, its Putty Tape Time.......
