I also got the goo in the PP starting area near nav 2 from the critters lvl 1 & 2. I seemed to get more drops of the goo there, than from ABG nav comm location from the actual dish dervishes themselves.
My TT did the mission for the ducttape as well, and my JE assisted him with all the refines so it was completable by non-jenqs with lvl 5+ build skills.
