I know this is an old post, but just found it while looking for info on Massey finish.
I used super glue on black paracord 500lb. I believe and didn't have any of the adverse reactions you mentioned. Maybe it has something to do with the dye that was used to make it green?
I soaked the edges of my paracord a little at a time as I was wrapping around the handle, then soaked it a bit more to make it all stick real good after the wrap was done. I really like the feel of a paracord wrap, feels very nice in the hand and doesn't have that slippery feeling that finished wood does, makes a nice firm grip.
