Sorry its TE....

When should I close it and how?
In the second picture we are looking at the gap itself, its between the TE sheeting and the TE, its about 1 mm wide and its too significant to ignore.
I need to cut off the excess sheeting to get to the TE then it would be more reviled.
Its glued with epoxy and the length of the gapped section is about 2 inches.
There should be a hinge in that place and I cannot just press it in tried that, there are epoxy drops there.

Thanks in advance
Alex
